Relay-Medium Power Multi-Control Voltage

The MR-Series Multi-Voltage Control Relays offer SPDT or DPDT 10 Amp contacts which may be operated by one of four input control voltages. A single relay may be energized from a voltage source of 24 Vdc, 24 Vac, 115 Vac or 230 Vac by wiring to appropriate input terminals.

Each relay position contains a red light emitting diode (LED) which indicates the relay coil is energized. Relays may be “snapped apart” from a standard four-module assembly and used independently.

These devices are ideal for applications where local contacts are required for system status, remote contacts for control of electrical loads and general purpose switching. They are suitable for use with HVAC Temperature Control, Fire Alarm, Security, Energy Management, and Lighting Control Systems.  When used for feedback the GSA-MM1 is the best fit since the active or inactive condition of the relay contact is supervised and monitored by the module without latching.  Other conditions which require latching, such as alarm, are best supported by the GSA-CT1 or GSA-CT2.
