Description
Product name: Honeywell MR-101/C/R Multi-Voltage Control Relay Price Bangladesh
Manufacturer: Honeywell
Product Overview
The Honeywell MR-101/C/R operates as a multi-voltage control relay designed for fire alarm auxiliary switching, HVAC controls, security setups, and building automation interlocks. Equipped with a Form C (SPDT) dry contact configuration, it provides switching for emergency functions such as door holder release, elevator recall, fan shutdown, and remote signal triggering.
Furthermore, the MR-101/C/R features selectable coil input wiring terminals accommodating 24 VDC, 24 VAC, 120 VAC, or 230 VAC power sources. Housed in a dedicated enclosure with a flame-retardant red ABS plastic cover, it includes an onboard red LED indicator that illuminates when the relay coil is energized.
Key Benefits
-
Multi-Voltage Input Selection: Accepts 24 VDC, 24 VAC, 120 VAC, or 230 VAC control power on designated wiring terminals.
-
Form C Contact Switching: Features SPDT dry contacts rated at 10 A @ 120/125 VAC and 7 A @ 28/30 VDC.
-
Visual Status Annunciation: Integrates an onboard red LED viewing port to confirm active relay coil energization without test equipment.
-
Flame-Retardant Enclosure: Enclosed within a backbox assembly fitted with a red ABS-94V0 plastic cover.
- Operating Duty Limitation: Designed for continuous-duty operation at 24 VDC, 24 VAC, and 120 VAC. The manufacturer states that continuous-duty operation at 230 VAC is not intended.
