User Manual

Hot-swap of a relay module containing shared relays will affect all protection
modules that are associated with the shared relays.

Hot-swap of a protection module with shared relays in different slots will
affect the associated relay modules.
Relays on Relay Modules

Relays 1 to 28 are of SPDT (Single pole, double throw) type and relays 29 to 32 are
of DPDT (Double pole, double throw) type.

Relays are software configured without any need for DIP switch settings. The
software configuration of relays is described in
Configuring a Relay Module via IMx-
M Manager.

Relays are based on flexible relay logic with Voting as well as and/or logic.

Relays can be configured as normally energized or normally de-energized.
Normally energized has the power on all the time until the relay is triggered. In
such case, relay goes into alert/danger upon power failure.
–
Default state for alert is energized.
–
Default state for danger is de-energized.
Figure 2 - 18.
Relay Connector Configuration.

Relays can be configured for latching or non-latching alert/danger.

Relays can be connected as normally open or normally closed.

Relays have redundant relay functionality.
–
Several relays can be configured to a single channel.
–
Relays associated to different protection modules can be configured to a single
channel.

Each relay module provides LED status indicator for each relay as described in
Relay Module (RLM) within LED Indicators.

For the physical layout of relay connectors, refer to Relay Module (RLM)
