A DPDT relay switching 24 V AC/DC or 115/230 V AC circuits for home safety systems
The Edwards-Signaling MR201/C is a double-pole double-throw relay designed for home safety and security systems. It switches loads across 24 V AC or DC and 115 V or 230 V AC supplies. The unit carries UL listing and weighs 0.85 lb. Installers use it to isolate control circuits from higher-voltage equipment.
The relay accepts four coil voltages without modification, reducing the number of spare parts a technician must stock. Its DPDT contacts allow simultaneous make-and-break switching for interlocking or redundant safety circuits. The 2 1/2 in depth fits standard enclosures. Buyers needing sealed contacts or a different mounting style should check alternative models.

The relay uses mechanical DPDT contacts rated for 24 V AC/DC and 115/230 V AC switching; follow the manufacturer's preventive-maintenance schedule for contact wear checks.
The coil is designed for continuous energisation at 24 V AC/DC or 115/230 V AC, so the contact current rating typically becomes the limiting factor before coil temperature does.
