New Original Phoenix Contact 2961105 REL-MR-24DC/21 Miniature Plug-in PCB Power Relay
1. Product Overview
REL-MR-24DC/21 (Order No. 2961105) is an original Phoenix Contact miniature plug-in electromechanical relay from the REL-MR series. Equipped with a 24 V DC coil and one single-pole changeover (SPDT) contact, this relay adopts standard through-hole pins for direct PCB soldering or plug-in assembly onto corresponding relay sockets.
The relay is designed for low-power signal switching and small load control in industrial automation systems. It is widely used to drive solenoid valves, indicator lamps, transfer sensor signals and expand PLC output circuits on packaging machines, conveyor systems, machine tool control panels and compact electronic modules. Its slim housing supports side-by-side dense arrangement on printed circuit boards to save installation space.
2. Main Functions
- Signal and Small Load Switching Achieves reliable make-and-break control for alternating current and direct current loads, transmitting control signals from controllers to on-site actuators.
- SPDT Changeover Contact Configuration Integrates normally open and normally closed contacts, enabling flexible circuit switching and signal selection for diverse control logic.
- Dual Mounting Compatibility Supports direct soldering on PCB or plug-in installation with matched relay bases, facilitating quick replacement during equipment maintenance.
- Low Power DC Coil Operation Low coil power consumption reduces load pressure on PLC transistor outputs and other control modules.
- Long Service Life Contact System AgSnO contact material effectively prevents contact welding and guarantees stable performance under repeated switching cycles.
- Effective Isolation Between Coil and Contacts Provides electrical separation between the control coil circuit and load circuit to reduce mutual electromagnetic interference.
- Wide Ambient Temperature Adaptability Maintains consistent switching performance under temperature fluctuations inside electrical control cabinets.
