GENERAL
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 (LEO) 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.
The Air Products & Controls MR-199 Heavy Duty Power Relays are designed for control applications where 30 amp DPDT contacts are required. The 24 VDC and 120 VAC relays are mounted in a rugged steel enclosure.
MR SERIES FEATURES (Excluding MR-199 Series)
- Each relay position may be energized from one of four input control voltages.
- Each relay position contains a red LED which illuminates when the coil is energized. This provides a timesaving convenience when checking an installed system, no metering is required.
- Single, dual, or triple relay modules may be “snapped apart” from a standard four-position master.
- SPDT or DPDT relays available.
- Available in dust-proof metal enclosures (with gray plastic cover on MR-101/C and MR-201/C) with LED viewing
- Red enclosure available on some models.
- Track mounting hardware to facilitate installation in standard cabinets.
- UL recognized relays rated at 10,000,000 mechanical
