The Unitronics URD-0004SM is a compact UniStream® Remote I/O solid state relay output module designed to provide reliable remote switching capability for industrial automation systems. As part of the Unitronics UniStream Remote I/O platform, it enables machine builders and control engineers to expand output capacity while maintaining flexible Ethernet-based communication architecture.
This module delivers four solid state relay outputs capable of switching AC or DC loads up to 110 V at 1 A per channel. Its slim 12 mm housing conserves valuable panel space while providing dependable operation in demanding industrial environments. Integration with UniStream controllers is straightforward using Unitronics UniLogic software and Ethernet Remote I/O adapters.
With 4 solid state relay outputs, 110 VAC/DC switching capability and 1 A output current per channel, the URD-0004SM is ideal for controlling contactors, indicators, alarms, solenoids and automation equipment within distributed control systems.
The URD-0004SM enables remote control of field devices through Ethernet-connected UniStream Remote I/O systems. By distributing outputs closer to machinery and process equipment, installation costs can be reduced while simplifying panel wiring and improving system scalability.
Solid state relay technology provides reliable switching performance without mechanical contact wear, making the module suitable for frequent switching applications and demanding industrial environments where long-term reliability is essential.
