The Tri-M Engineering IR104 PC/104 Industrial Relay Module is a high density digital I/O relay module, designed for industrial applications requiring power switching, on/off control, and equipment automation.

With 20 opto-isolated digital inputs, 20 SPST outputs, quick-disconnect screw terminal mating plugs, and selectable IRQ and Input Change Flags, this highly versatile design is ideal for any industrial control and COTS application requiring input isolation from external monitor and control signals.

The IR104 operates in industrial environments, and its PC/104 embedded systems design allows up to four IR104 modules to be stacked together.

Product Family: IR104, 1RIO4, IR 104, IR-104
