SMR-8P Alarm Relay

SMR-8P Alarm Relay

The SMR-8P Alarm Relay is a collective alarm component for switching equipment. It is equipped with 8 independent alarm inputs,one phase-assigned switching output for indicator light, as well as one neutral changeover contact for outputting collective alarms to a control room or for an acoustic alarm.

The SMR-8P Alarm Relay is equipped with a code switch that can be used to set the working mode for each individual alarm input. The SMR-8P is available in a 230V AC and a 24V DC variant. Adaptations to customer requirements are possible. Generating of new fault value as per DIN 19235.

Note: If more than 8 alarm inputs are required, this can be done using the SMRG-4 alarm relay and the SME-12 expansion modules. This option enables a maximum of 52 alarm inputs (more details at: SMRG-4 Alarm Relay).
