I/O Modules

I/O Modules
I/O modules are electrical components used for device communication, device control and operation timing. They can connect directly to external loads like sensors, actuators, motors and valves to send and receive feedback to a control system when the load is energized. They can also be used as accessory devices for PLCs and HMIs.
Modern I/O modules are compatible with advanced industrial communication protocols, built with Ethernet ports and supporting TCP/IP, Modbus, Sixnet, ARP, UDP, HTTP and many other network modes. I/O modules typically offer RS-485 serial and USB connectivity as well.
Simple modules will use pin connectors and provide feedback for up to four circuits. More complex equipment can swap between and automatically configure several channels, with programmable feedback states.

1781-Series of Slim input and output modules and solid-state relays provide compatibility with a variety of manufacturers' miniature modules. Slim modules have a hold-down screw, and can be used in mounting boards where vibration and shock are not of concern.

- DIN-Rail Mountable Single Point Output Modules
- Plug into Mounting Boards for 0.6" Modules
- Zero Voltage Turn-On for AC Modules
- Barrier Strips Accept 14 to 28 AWG Wire
- Industry Standard Color Coding Black (AC) and Red (DC)

WRC4 Series Discrete I/O expands WRC's complete line of discrete I/O modules. These modules provide an indication LED and replaceable fuse. They also meet an industry de facto standard pin-out.

- AC Modules Have High Current Thryistors with 100 Amp Surge Capability
- Plug Into Mounting Boards for 0.6" Modules
- Zero or Random Turn-On Available in AC Modules
- UL Recognized, CSA Certified, CE Compliant
- Industry Standard Color Coding Black (AC) and Red (DC)
