Description

The MR-810 Series Relays offer SPDT 10A resistive contacts which may be operated from either a 24VDC or a 24VAC control input. The input voltages are polarity sensitive and diode protected. The common output contact contains a 10A fuse which protects the contacts and load from over current. Each relay position contains a red LED which indicates when the relay coil is energized. Relays may be "snapped apart" from a standard 8 module assembly and used independently. Relays are available with snap track and mounting hardware. A single MR-811, MR-812, MR-814 or MR-818 is also available mounted in a sturdy NEMA 1 enclosure.

These devices are ideal for applications where protected control of up to 10A electrical loads are required. They are suitable for use with HVAC, Temperature Control, Fire Alarm, Security, Energy Management and Lighting Control Systems.
