£127.75
The Unitronics URD-0004SK is a compact and reliable 4-channel solid state relay output remote I/O module designed for industrial automation, machine control and distributed Ethernet I/O applications. As part of the advanced Unitronics UniStream Remote I/O series, it provides high-speed switching performance while eliminating the mechanical wear associated with traditional electromechanical relays.
Engineered for demanding industrial environments, the URD-0004SK delivers dependable solid state switching for controlling contactors, indicators, solenoids and other field devices. Its slim DIN rail-mounted design allows easy installation within control panels while supporting scalable UniStream Remote I/O architectures.
Featuring 4 solid state relay outputs rated for 240 VAC/DC at 0.5 A, the URD-0004SK offers fast response times, long operational life and reduced maintenance requirements. Integrated LED status indicators simplify diagnostics and commissioning while ensuring reliable operation across a wide operating temperature range.
The Unitronics URD-0004SK provides dependable solid state output control for industrial automation systems where high switching frequency, long service life and minimal maintenance are important. Unlike mechanical relays, solid state outputs have no moving contacts, reducing wear and increasing operational reliability.
When integrated into a UniStream Remote I/O network, the module enables distributed control of machinery and process equipment while maintaining reliable communication with the central controller. Its compact width helps maximise cabinet space efficiency in modern automation installations.
