UIS-WCB2 UniStream I/O Expansion Module – 14 Digital/Analogue Inputs and 12 Transistor Outputs

Why Choose the Unitronics UIS-WCB2 UniStream Wide Mixed I/O Module?

The Unitronics UIS-WCB2 is a versatile UniStream Wide mixed I/O expansion module designed to extend the capabilities of Unitronics UniStream PLC systems. The module combines multiple input and output signal types in a single device, allowing automation engineers to manage digital, analogue and temperature signals while controlling loads through high-speed transistor outputs.

Part of the UniStream Uni-I/O Wide module family, the UIS-WCB2 provides a high density of inputs and outputs in a single expansion unit. Wide modules are approximately 1.5 times wider than standard Uni-I/O modules, allowing more I/O channels while reducing the number of modules required in complex control systems.

The module integrates digital inputs, analogue inputs, temperature inputs, transistor outputs and analogue outputs, making it ideal for applications that require mixed signal processing. It can be installed directly on the back of a UniStream HMI panel with a CPU-for-Panel or mounted on a DIN rail using a local expansion adapter.
