URD-0008CH – Unitronics DO8,Source,24VDC/0.5A,10R

Why Choose the Unitronics URD-0008CH Digital Output Module?

The Unitronics URD-0008CH is a compact 8-channel transistor digital output module designed for the UniStream Remote I/O platform. It provides eight sourcing digital outputs for controlling actuators, indicators, relays and other field devices within distributed industrial automation systems.

Installed as part of a UniStream remote I/O assembly, the module communicates with a remote I/O adapter over Ethernet while the main PLC controller manages system logic. This distributed architecture allows I/O modules to be located close to machines or sensors, reducing wiring complexity and improving scalability in industrial control systems.

With 24 V DC transistor outputs rated up to 0.5 A per channel, the URD-0008CH delivers fast and reliable switching performance for modern machine automation environments.
