The MR Series multi-voltage control relays offer SPDT or DPDT contacts which may be operated by multiple input control voltages.Each 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 for control of electrical loads and general-purpose switching. They are suitable for use with HVAC, temperature control, fire alarm, security, building automation, and lighting control systems.
