UIS-WCB1 UniStream I/O Expansion Module – 14 Digital/Analogue Inputs and 12 Relay Outputs

Why Choose the Unitronics UIS-WCB1 UniStream Wide I/O Module?

The Unitronics UIS-WCB1 is a powerful UniStream Wide I/O expansion module designed to provide a comprehensive mix of inputs and outputs for Unitronics UniStream PLC systems. This versatile module integrates multiple signal types in a single device, making it ideal for complex automation systems that require digital, analogue and temperature monitoring with flexible output control.

Part of the UniStream Uni-I/O Wide module family, the UIS-WCB1 is approximately 1.5— wider than standard Uni-I/O modules, allowing a higher density of I/O channels within a single module. It can be attached directly to the back of a UniStream HMI panel with a CPU-for-Panel or mounted on a DIN rail using a local expansion adapter, enabling flexible control panel layouts.

The module provides a mixed I/O configuration including digital inputs, analogue inputs, temperature inputs, relay outputs, transistor outputs and analogue outputs. This all-in-one design reduces the number of separate modules required in automation systems while maintaining precise signal control and monitoring.
