The Air Products and Controls MR-101-CR is a 24VDC, MR Series Relay with SPDT (10A) contacts. A single relay may be energized from a voltage source or VAC by wiring to appropriate input terminals. The MR-101-CR contains a built-in, red light-emitting diode (LED) which lights up to indicate an energized coil. The relay can be “snapped apart” from a standard four-module assembly and used independently.
This device is perfectly suited for applications where local contacts are required for system status, remote contacts for control of electrical loads, and general purpose switching. Ideal for HVAC, Temperature Control, Fire Alarm, Security, Energy Management, and Lighting Control Systems.
