wire transmitters and dry contacts. For maximum channel-to-channel isolation, externally powered analog and digital inputs may be selected.

Status-at-a-glance indicators offer instant visual notification of I/O system problems. Each I/O module has a bi-color Pass/Fail LED to display the on-line diagnostic status. Digital I/O status LED’s are provided for each point. Analog Input modules have a unique feature. Each input point has two LEDs to indicate input under/over range conditions due to open and shorted field devices. The green LED, when lit, indicates the input is in a normal range. The Red LED, when lit, indicates the input is under or over range, typically meaning it is open or shorted.
