ROA16 Discrete Output Field Termination

Discrete Output Field TerminationDiscrete Output Field Termination

The Automation and Electronics, Inc. ROA-16 is a relay output board designed to provide expansion of sixteen additional relay outputs for our SRTU-121, 604-SLCR and 608C controllers.

The ROA-16 provides sixteen Form A (normally open) relay outputs. Each relay is driven by a MOSFET which turns on and off according to the written data from the processor. Each relay output has an LED to provide an visual indication when the relay is energized.
