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 power relay belonging to the REL-MR series. It features a single SPDT (1 changeover) contact configuration with AgSnO contact material and a 24 V DC control coil. Designed for direct PCB soldering or plug-in installation onto matched relay sockets, this compact relay supports zero-spacing side-by-side arrangement on circuit boards.
It serves signal switching and small load control tasks within automation control systems, widely used for PLC output expansion, solenoid valve drive, indicator light control, sensor signal switching on packaging machinery, conveyor equipment, machine tool control panels and small electronic control modules. The standardized pin layout ensures convenient circuit design and component replacement.
2. Main Functions
- Electrical Signal & Small Load Switching Realizes on-off switching of AC and DC loads, transferring control signals from controllers to actuators such as valves and signal lamps.
- SPDT Changeover Contact Operation Equipped with normally open and normally closed contacts, enabling flexible circuit selection and signal routing.
- Compact PCB Plug-in Mounting Standard through-hole pins support direct soldering on PCBs or plug-in assembly with dedicated relay bases for quick maintenance.
- Stable Low-power DC Coil Driving Low coil power consumption reduces controller output load, compatible with standard PLC transistor outputs.
- High Mechanical & Electrical Service Life Optimized contact structure ensures long cycle life under rated load conditions for continuous industrial operation.
- Wide Operating Temperature Adaptability Maintains reliable switching performance under fluctuating ambient temperatures inside control cabinets.
- Built-in Basic Insulation Barrier Sufficient isolation between coil circuit and contact circuit prevents mutual interference in mixed signal circuits.
