Connect switches, transmitters, actuators, and other equipment to your programmable logic controller (PLC) for complex automation jobs. To operate, attach these modules to a PLC power supply and a processor (not included). Once the processor has been programmed and your system has been configured, the input modules receive an electrical signal from your switches or sensors and transfer it to the processor. The processor then communicates with the output modules, which send a signal to your receiving devices, such as circulation pumps or motor starters. Connect up to 10 different modules per power supply and processor. Mount them to a 35-mm DIN rail.

Rated IP20, these modules prevent your fingers from touching internal components and accidentally shocking yourself. With various domestic and international certifications, they meet strict standards for quality and safety. Some meet additional military standards for electrical connections.

Digital Modules

These modules send and receive on-off or high-low electrical signals to and from your equipment. Configure digital input modules to receive these signals from devices such as push-buttons and proximity switches. Choose digital output modules to activate instruments that switch on and off, such as indicator lights, buzzers, and solenoid valves. Digital input/output modules combine both functions into one unit, saving space and wiring on your PLC setup.

Modules with PNP/NPN inputs can automatically read both signal types without needing to select the polarity.

Modules with transistor signal outputs are used for handling DC loads. They’re faster and have a longer lifespan than relay outputs. Triac signals are similar to transistors but handle AC loads. Relay signals are slower than triacs and transistors, but they can handle higher loads for either AC or DC. Because of their moving parts, they wear out quicker than transistors and triacs.

Analog Modules

Use these modules to send and receive electrical signals within a defined range of values. A dial on the modules lets you set your preferred range. Pair analog input modules with temperature sensors, pressure transmitters, and other devices that can generate these signals. Analog output modules convert these signals to make precise adjustments on your equipment. They’re commonly used with motor speed controls and flow-adjustment valves. Analog input/output modules are capable of both functions to save space for a simpler automated system. Choose analog temperature-control-loop modules to control temperatures without slowing down your processor with extra tasks. They’re equipped with both inputs and outputs.

Connect and communicate with multiple automation devices simultaneously, such as HMIs, motor speed controls, supervisory PCs, and additional PLC racks. These modules allow several systems to talk to one another—within your facility and beyond—letting you expand your automated processes over numerous interconnected networks. Choose a module that supports the communication protocol of the systems and equipment you’re connecting to.

Rated IP20, these modules prevent fingers and other objects greater than 12.5 mm from making contact with live circuits. They’re also UL and C-UL listed, CE marked, and CSA certified to meet various domestic and international safety standards.

DIN rail-mount modules attach conveniently to other modules on your PLC rack.

Processer socket-mount modules plug in directly to the front of your corresponding processor, so they won’t take up any additional space on your DIN rail.

Modules with remote input/output compatibility can transmit data between sensors and actuators without long runs of cable for each device. Mount them in your control room, and communicate with automated equipment hooked up far away.

No need to program multiple PLCs—these modules expand your automated system, keeping everything conjoined and configured on one processor. Use them when you’re out of space on your DIN rail or need additional input/output functions.

These modules meet NEC safety standards, so they can be used in hazardous locations. They’re also rated IP20 to protect your fingers from touching live wires. Modules are UL and C-UL listed, CE marked, and CSA certified, meeting strict domestic and international safety requirements.

Control modules connect directly to the main PLC rack. Insert them in between the processor and the first input/output module.

Interface modules attach to a separate expansion rack, which requires its own power supply (not included). The interface comes with an end plate, which caps off each rack and ends communication with the processor. A maximum of three expansion racks can be hooked up from the main PLC rack.

Use the expansion cords (sold separately) to connect the control and interface modules together. Cords are also IP20 rated, UL and C-UL listed, CE marked, and CSA certified. Total cord length for your entire system should not exceed 39 ft.

Design and operate up to six simultaneous programs without symbols or technical language—the on-screen instructions use simple English. These PLCs combine the functionality of a relay, timer relay, and switch in one unit so you can program complex automation jobs. All have memory backup to retain programming during power outages. Mount to 35-mm DIN rail.

Add expansion modules to increase the number of inputs and outputs. Use either module on its own, or add one of each, but two of the same module won’t work together.

Remote timer panels monitor and adjust up to eight timers while the controller is operating.

Combine the functionality of a programmable logic controller (PLC) and the accessibility of a development board. Built around a Raspberry Pi and an Arduino-enabled microcontroller, these controllers use open-source software to make programming and troubleshooting convenient. Use them in your automated system to monitor sensors, control actuators, and support Internet-of-Things functionality, such as wireless communication with sensors and connection to cloud-computing services. Their plastic housing keeps the inner electronics protected in industrial environments. Controllers meet UL 94 V-0 standards for safety, and they’re rated IP20 to prevent fingers and other objects greater than 12.5 mm from making contact with live circuits. Mount them to DIN rails inside control cabinets.

Create a system of sensors and actuators that you can remotely update, view measurements from, and receive error messages in real time. IO Link systems minimize downtime by locating issues such as cut cables or dirty sensors quickly. They send only digital signals to your PLC, regardless of whether your sensors and actuators send digital or analog signals. Because these systems send digital signals, they’re more reliable and less prone to data error and signal loss than analog signals. It also means you don't have to use expensive shielded cables since they resist EMI.

When retrofitting an existing system, you'll need to make sure your PLC can incorporate IO Link. Check with your PLC manufacturer—most have hardware that allows you to upgrade your PLC to run IO Link.

Controllers communicate between your sensors and actuators and your PLC. They are required. Setting memory automatically stores your settings and restores them once your device is back online. This eliminates needing to program a device again when you replace or fix it. Surface mount controllers let you mount controllers on equipment such as tanks and conveyors. By mounting them on your equipment, you save space in your control cabinet. They use M12 connectors. DIN-rail mount controllers are designed to mount inside your control cabinet, so you can access all your process control devices in a central location. They include RJ45 Ethernet ports to support JSON and MQTT IoT (Internet of Things) protocols, allowing you to link the system directly to your web server to upload information to the Cloud. Connect these ports with RJ45 cords.

Expansion modules increase the number of inputs and outputs in your IO Link system, so you can add more sensors and actuators to your network. Connect multiple devices to each expansion module using M12 connectors, without needing to wire your devices inside a control cabinet. They transmit signals from multiple devices with a single cord. Expansion modules are optional, but when used, they must connect to a controller. Mount them on your equipment to save space in your control cabinet.

Converters translate analog signals to digital signals, making sensors and actuators IO-Link compatible. They are required to connect analog components to controllers and modules.

Protective caps prevent dust and debris from harming M12 connections when they're not in use. They also help maintain IP ratings by covering unused ports. Stainless steel protective caps have a neoprene gasket, which helps maintain IP69K ratings.

IP rated components block out dust and withstand some water, so they do not require an enclosure. Ports that are unused must be capped to maintain their rating. IP65 rated components can be rinsed. IP66 rated components withstand washdowns. IP67 rated components can be temporarily submerged in water. IP69K rated components hold up to high-pressure and high-temperature washdowns.

Note: Sockets may have extra holes on their face that are not used.
