The Air Products & Controls MR Series Multivoltage 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 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 con-tacts are required for system status, remote contacts forcontrol of electrical loads and general purpose switching.They are suitable for use with HVAC, Temperature Con-trol, Fire Alarm, Security, Energy Management, and Light-ing Control Systems.

The Air Products & Controls MR-199 Heavy Duty PowerRelays are designed for control applications where 30-amp DPDT contacts are required. The 24 VDC and 120VAC relays are mounted in a rugged steel enclosure.
