Omnex DS-900 Series of DIN Rail Mount
Remote I/O Cordless Wires

The OMNEX DS-900 Series of DIN Rail Mount Remote I/O Cordless Wires™ enable users to move multiple points of discrete and analog updates back and forth between two locations. Flexibility is offered by allowing the user to "stack" different combinations of I/O on the paired RF modules depending on site requirements. This FHSS product is ideal for reliably moving numerous signals through high interference environments without installing cable and conduit.

Typical applications include process control, multiple pressure, temperature, level and flow, alarm and switch monitoring and control.

I/O Configuration Options

Up to eight (8) modules can be used per pair of DS-900's to expand the number of discrete and/or analog signals being moved between two sites (each input module being paired with a corresponding output module at the other location). For example

Maximum Discrete I/O Configuration

Maximum Analog I/O Configuration

Any combination of I/O (up to eight (8) paired modules)
