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
notication 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 eld 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.
