4.4.9 Analogue Output (Terminals 27 & 28)
Figure 4.13: IPM Relay Electrical Connections: Analogue Output
The IPM relay is provided with a 4-20mA analogue output. It is provided with a wide ranging DC
voltage input at 7.5VDC to 36VDC.
4.4.10 Output Relays (Terminals 29, 30, 31, 32, 33, 34, 35, 36, 37 & 38)
Figure 4.14: IPM Relay Electrical Connections: Output Relays
The IPM relay has three (3) different types of output relays. The Main Contactor Relay (MCR) is
intended to open and close the outlet‟s contactor as part of its control and protection functions. The
Alarm Relay (ALM) can be programmed to close at specified alarm points for different protection
functions. The Circuit Breaker Relay (CBR) is intended to provide a back-trip to an upstream circuit
breaker for faults such as frozen contactor and short circuit.

Main Contactor Relay (MCR)
The MCR output has two poles, one is a
changeover contact and the other is a
normally open contact.
Either of these contacts can be used to
trip the main contactor for the outlet.
The other MCR contact can then be used
as an indication output.
Alarm Relay (ALM)
The ALM output is a normally open
contact.
Function is programmable.
Circuit Breaker Relay (CBR)
The CBR output is a changeover contact.
The CBR output is intended to initiate a
back-trip to an upstream circuit breaker
via a shunt or undervoltage coil.
