3.1 1600A Interface Board
The 1600A Interface Board Figure 8 is connected to a set of Terminal Blocks on the DIN Rail (Figure 6 and
Figure 7.) The Terminal Blocks are labeled “NO COMM” “C”, “NO” and “NC”. The Interface PCA,
mounted on the back of the Display Panel, will de-energize the No Comm/Fault relay in the event there is a
Communication Fault with any activated device. A ‘No Communication Fault’ condition will create a ‘short’
between the ‘Common’ and ‘Normally Closed’ contacts, and create an open between the ‘Normally Open’ and
‘Common’ relay contacts. This is required for fail-safe operation. There is a two-minute delay before any
active device will trigger a no communication condition.
