3.8 Relay Configuration

Overview.

Relays – can be energized by alarms, logic equation results (math software option enabled by installation of the appropriate
software key), digital inputs, real time events (timer software option enabled by installation of the appropriate software key) and
totalizer wrap signal (totalizer software option enabled by installation of the appropriate software key)

External totalizer count function – external counter can be driven only by Module Type 3 (4-relay module) fitted in module
positions 4, 5 or 6 (see Section 5.2, page 66).

Polarity – allows fail-safe settings
