Compact PLCs

PLC Shown with Two Expansion Modules (Sold Separately)

Support for up to 188 inputs and outputs—these PLCs are ideal for basic tasks where more advanced PLCs would be overkill, such as operating lighting and HVAC systems. They’re also known as smart relays. Connect these PLCs to your Ethernet network to control devices anywhere in your facility. They use an open communication protocol, so you can mix and match devices from different manufacturers. Mount them to 35 mm DIN rail in your electrical cabinet or use mounting brackets (sold separately) to secure them to a flat surface.

You’ll need a license key (sold separately) for the manufacturer’s software. Write your program in common PLC languages, such as Ladder Logic and Structured Text, then transfer your program to the PLC with an Ethernet cord. Use the software to monitor, test, and troubleshoot issues in real time. Add a memory card to back up, store, and transfer programs to multiple machines.

These PLCs have digital inputs and outputs. PLCs with relay outputs are ideal for devices that switch a few times per minute, such as compressors. PLCs with transistor outputs are ideal for devices that switch multiple times per second, such as indicator lights and stepper motor drives. They’re PNP outputs, also called sourcing outputs, so they work only with NPN devices. If you need to connect different devices, use an output converter or signal converter (both not included).

PLCs with analog inputs receive signals from devices that monitor temperature, pressure, and other measurements that vary.

Screw terminals are the most common wire connection—insert your wires and tighten the screws to secure them. Spring-clamp terminals hold wires with a clamp instead of screws, so connections stay secure, even with vibration.

Add expansion modules to PLCs when your system grows or needs new functionality. All modules have an LED status indicator to show the device is powered and running.

PLCs with Display

These PLCs have a screen and keypad that let you adjust timers and change basic settings without connecting to your computer. You can also view system errors and warnings for quick troubleshooting.

Fast-Processing Open-Source PLCs

When milliseconds matter, these PLCs don't have to wait for your network—they process complex data and run code locally. The result is real-time performance in the field, plus cloud connectivity when you want it, for truly uninterrupted operation. These PLCs support Python, C++, Bash, and other open-source languages, so you can program them in the one you know. You can also use customizable libraries to your advantage.

Write code from anywhere—on any device and browser—using the manufacturer’s free web-based software. When you’re ready, transfer your program to the PLC with an Ethernet RJ45 cord, Bluetooth, or Wi-Fi. In addition to wireless communication, these PLCs have a range of hardwire connections, including digital inputs and outputs, Ethernet, and serial terminals. This means they can control a fully wireless system, a wired setup with legacy equipment, or a hybrid of both. Mount them to 35 mm DIN rail.

Easy-Program PLCs

Easy-Program PLCs Are Programmed with Plain English Commands

Use plain English and simple if-then statements to program these PLCs—no need to learn a new programming language. With support for up to 30 inputs and outputs, they can automate tasks such as controlling part of your conveyor line. Just one of these PLCs can handle hundreds of lines of instruction, enough to operate six programs at the same time. These PLCs have memory backup, so you won’t lose your programs during power outages. They have digital inputs and outputs to send and receive binary signals—such as on-off or high-low—to and from your equipment. Mount them to 35 mm DIN rail.

Add expansion modules to the PLC when your system grows. Add remote timer panels to monitor and adjust timers while the PLC is running.

PLCs with Hand-Held Programmer

Write and edit programs right at the PLC with a programmer that fits in your hands. Without the need for software and a computer, you can start programming out of the box in minutes. Use the display and push buttons to build your program—simply select options from the menus to write your instructions. The programmer runs on power from the PLC—just connect it with the included cord. Because it’s small and stores a copy of the program, you can easily carry it to other PLCs when you need to clone a setup.

Open-Source PLCs

Kick-start your automation with example code and customizable libraries from the Arduino ecosystem. Use the manufacturer’s free software to program these PLCs with Arduino or a standard PLC language you’re comfortable with. When you’re ready, transfer your program to the PLC with a USB-C cord. Use the software to monitor, test, and troubleshoot issues in real time.

These PLCs support up to 88 inputs and outputs—enough to automate lighting or HVAC controls. They’re also known as smart relays. They have digital relay outputs that are ideal for loads that switch a few times per minute, such as compressors. However, they’re not designed for devices that switch multiple times per second, such as stepper motor drivers. Connect these PLCs to your Ethernet network to control devices anywhere in your facility. They use an open communication protocol, so you can mix and match devices from different manufacturers. Mount them to 35 mm DIN rail in your electrical cabinet.

PLCs with Wi-Fi have cloud connectivity that lets you program, monitor, and update them from anywhere. They also have Bluetooth to make initial setup easy—you can wirelessly configure them at close range. These PLCs send alerts directly to your mobile device, so you can quickly respond to issues.

PLCs with RS-485 terminals let you integrate legacy equipment and other serial devices into your system.

Add expansion modules to these PLCs when your system needs more inputs and outputs or new functionality. All modules have an LED status indicator to show the device is powered and running.

Miniature PLCs

Get only what you need—up to 36 inputs and outputs—to save space and money. These PLCs are best for controlling simple setups, such as part of your conveyor line. They’re smaller than a deck of cards, so you can stick them inside equipment with the included adhesive mounting pad. Alternatively, mount them to 35 mm DIN rail with a bracket (sold separately).

Once you download the manufacturer’s free software, you can program in Ladder Logic or Flow Chart. When you’re ready, transfer your program to the PLC with a USB Mini-B cord. You can also set up the USB port for serial communication to your devices.

The transistor outputs don’t have moving parts, so they’re ideal for fast-switching, low-power devices. Since they’re NPN outputs, also called sinking outputs, they provide the ground connection when on. If you need to connect different devices, use an output converter (sold separately). Wire connections without turning screws with the spring-clamp terminals. LED status indicators show you when inputs and outputs need troubleshooting.

PLCs with analog inputs or outputs help you automate based on measurements that vary, such as pressure or speed readings.

PLCs with thermocouple inputs help you automate based on temperature readings.

Output Converters

Converter Connected to PLC

Turn the PLC’s low-power transistor signals into relay contacts when you need to switch high-power loads, such as motors. You don’t need additional programming—just connect these converters to the 6-pin output on the PLC with the included cord. These converters must be connected to a power supply since they don’t draw power from the output terminal.
