- Each relay contains a high-intensity LED indicating an energized coil status
- UL recognized relays rated at 10,000,000 mechanical operations
- /C versions mounted in enclosures with LED viewing port(s)
- /C/R versions with red covers for NYC and other uses
- /T versions come complete with track mounting hardware which facilitates installation in standard cabinets
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.
