Air Products and Controls 636-093 MR-201 DPDT Relay

Air Products and Controls MR-201 DPDT Relay is a multivoltage, DPDT control relay in the MR Series that switches two independent circuits from a single control input. Available in two mounting configurations—MR-201/T track-mounted and MR-201/C enclosure-mounted (gray ABS cover)—it uses a DPDT contact arrangement rated at 10 A for resistive loads and supports coil voltages of 24 VDC, 24 VAC, 120 VAC, or 230 VAC. The MR-201/T variant ships with track mounting hardware, while the MR-201/C version is UL-listed (enclosure-mounted) for integrated use in control panels. These relays are commonly used in building automation and fire alarm control networks to interface low-voltage control signals with higher-current devices.
