Description
Product name: Air Products & Controls MR-201/C Relay Assembly Price in BD
Brand / Manufacturer: Air Products & Controls (APC / Space Age Electronics)
Product Overview
The Air Products & Controls MR-201/C functions as an enclosure-mounted multi-voltage control relay assembly designed for fire alarm circuits and auxiliary safety control applications. Technicians utilize this relay assembly to switch auxiliary equipment loads, HVAC fan shutoff systems, and emergency door holder circuits based on control panel signals.
Furthermore, the MR-201/C supports multi-voltage operation and energizes from a single input control voltage source. Specifically, installers connect power to appropriate terminals using $24\text{ (18–35) VDC}$, $24\text{ VAC}$, $120\text{ VAC}$, or $230\text{ VAC}$ inputs. Additionally, DC input control terminals require strict polarity verification during installation.
Key Features
-
Multi-Voltage Input Options: Operates from $24\text{ (18–35) VDC}$, $24\text{ VAC}$, $120\text{ VAC}$, or $230\text{ VAC}$ input control sources.
