Input/Output Modules for Programmable Logic Controllers
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. 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. 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 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.

End Plates for Programmable Logic Controllers

Used with PLCs, these end plates close off your system’s processes—telling the processor that there are no more inputs or outputs to communicate with. They also protect your modules’ circuitry from debris. Mount them to a 35-mm DIN rail.
These end plates meet NEC safety standards for use in hazardous locations. Rated IP20, they prevent your fingers from touching internal components and accidentally getting shocked. They are also UL and C-UL listed, CE marked, and CSA certified—meeting various domestic and international certifications for stringent safety requirements.

Expansion Modules for Programmable Logic Controllers
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.

IO Link Controllers and Modules

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.
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.
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. 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.

Signal-Conditioning Ultra-Thin Signal Relays


Also known as input modules, these relays condition electrical signals into signals for PLCs and microprocessors and prevent power surges from reaching these devices. They are extra narrow to maximize space inside your control cabinet. Mount to 35 mm DIN rail.
