Relay-Style Interposing I/O Terminals
Field Wiring
Power for operation of the relay coils must be provided by an external 24V DC
power supply. This power must be provided to both the main base and the
expansion base. Connection of this external power supply is made at the
terminals A17 & A18 (B17 & B18 for the expansion base). This power
connection is for the relay coils only. User loads must be powered by an
external source.
Each relay, status LED and fuse is labeled to indicate the specific point on the
VersaMax output module they are associated with. Components labeled A1-
A16 correspond to points Q1-Q16. Components labeled B1-B16 correspond to
points Q17-Q32. Each point is associated with 3 terminal connections, labeled
NO (Normally Open), C (Common), and NC (Normally Closed). User loads may
be connected between C and NO, C and NC, or both.
