Relays, Relay RL Status | Emerson Process Management MSP-ULOG1

Relays

Relay outputs 1 to 4 are normally On Point/Off Point relays which may be used to start/stop pumps. They normally energise at one level and de-energise at a different level.

Alternatively, they may be programmed as out-of-limits alarms such that they are energised between defined points and will de- energise outside the defined limits. They may also be programmed to perform a variety of auto-sequences and auxiliary functions, such as logging a memory nearly full alarm.

Relay output 5 is normally a fail safe fault relay but may be re-allocated to another duty.

Relays can be set-up easily using the Relay Wizard, accessible by navigating to the RELAYS menu screen.
