There are 3 versions of the Relay Output module for each operating voltage (48, 125 and 250 Vac), as follows:
Version
• Option
• Base 1
• Base 2
The option version provides phase B and C control functions for Single Pole Trip (SPT).
All 9 version/voltage variants share components of the same PC Board; the slight differences are shown on
1611C27 (sheet 1). The 3 versions are plugged-in and permanently secured (via brackets) to the following con-
nectors on the Interconnect module.
Version
• Option
• Base 1
• Base 2
Connector JB connects (via the Interconnect module) to the Microprocessor module's digital I/0 interface.
Connector JA connects relay contacts through the Backplane module to the outside world.
Opto-isolators U1, U2, U3 and U4 interface logic level output signals from the Microprocessor module to relay
driver transistors (Q1 through Q4, respectively).
Output relays K1, K2, K5, K6, K9, K10 provide desired control operations. Reed relays K3, K4, K7, K8 monitor
the breaker trip control circuit current.
Connector terminals are assigned the following functions ( see Table C-1 ):
