Relays On Relay Modules - SKF Multilog On-Line System IMx-M User Manual

Protection
Relays

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
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.


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.
–
–

Each relay module provides LED status indicator for each relay as described in
Relay Module (RLM)

For the physical layout of relay connectors, refer to
Connections.
