Wiring external devices to an RLY-6 interface module
To connect external devices to an RLY-6 interface module, use the two DB-9M connectors
on the rear cable assembly panel for the interface module.
For the pin assignment of these connectors as viewed from the frame side of the connector,
see Figure 23: RLY-6 DB-9M connector pinout.
If a DB-9F is plugged into the connector labeled CH. A I/O, relays 1 to 3 are available on that
connector. The connector labeled CH. B I/O has the contacts for relays 4 to 6.
Note:
In Figure 23: RLY-6 DB-9M connector pinout, the labels on the pins apply to either
connector. For example, #1/4 COM refers to the wiper of relay 1 if it is connected to CH. A
and the wiper of relay 4 if it is connected to CH. B.
