The MR204/C gives an installer four independent control relays in one dustproof metal enclosure, each energized from whichever of four common voltages the job already has on hand.

Built for the commercial fire installer

Each of the four relay positions wires to 24 Vdc, 24 Vac, 115 Vac, or 230 Vac independently, and a red LED at each position lights when its coil is energized - a fast visual check with no meter required. Positions can be snapped apart from the four-module assembly and used independently if a job only needs one or two relays. Suitable for HVAC, fire alarm, security, energy management, and lighting control applications wherever local status contacts or remote load control are needed.

Key features

  • Four DPDT relay positions, each independently voltage-selectable (24 Vdc, 24 Vac, 115 Vac, 230 Vac)
  • Red LED per position confirms coil energization without a meter
  • Snap-apart design - single, dual, or triple modules can be separated from the four-position master
  • Dustproof metal enclosure with LED viewing holes
  • 10A contact rating, UL recognized relays rated for 10 million mechanical operations

System requirements

18 ga. CRS enclosure with 1/2 in conduit knockouts (top and bottom). Rated -58°F to 185°F ambient.

FAQs

Are these SPDT or DPDT relays?
DPDT. Each of the four positions provides double-pole double-throw contacts rated 10A @ 125 Vac.
Can I use just one or two relay positions?
Yes. Single, dual, or triple relay modules can be snapped apart from the four-position master assembly and used independently.
Do all four positions need the same input voltage?
No. Each relay position is wired to its own choice of 24 Vdc, 24 Vac, 115 Vac, or 230 Vac independently.
