The MR Series Multi-Voltage Control Relays offer SPDT or DPDT contacts which may be operated by multiple input control voltages. Each multi-voltage control relay section contains a red LED, which indicates the relay coil is energized. Relay sections may be snapped apart from standard four- or eight-section assemblies and used independently. These relays are ideal for applications where local or remote contacts are required to control electrical loads and general-purpose switching. They are suitable for use with HVAC, temperature control, fire alarm, security, lighting control and building automation systems.
