1600A-N1P
3.1 1600A Interface Board
The 1600A Interface PCA is connected to a set of Terminal Blocks on the DIN Rail (
and .) The Terminal Blocks are labeled “NO
COMM” “C”, “NO” and “NC”. The 1600A Interface PCA, mounted on the inside of the top panel of the
enclosure, will de-energize the on-board relay in the event there is a ‘No Communication Fault’ condition with
any activated device. A ‘No Communication Fault’ condition will ‘short’ the common and normally closed
contacts, and creates an open between the normally open and common relay contacts of the on-board relay.
This is required for fail-safe operation. There is a two-minute delay before any active device will trigger a no
communication condition.
