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.
