New Original Phoenix Contact 2966171 PLC Interface Relay Module
Product Overview
Article number 2966171 corresponds to the PLC-RSC-24DC/21 relay module, a classic DIN rail mounting interface component under Phoenix Contact PLC-INTERFACE series. It is an integrated assembly consisting of a fixed terminal base and a detachable plug-in miniature electromagnetic relay. Designed for industrial control cabinets, this module acts as an isolation bridge between PLC low-power digital output signals and field execution loads. It receives 24 V DC control signals from programmable logic controllers and switches external loads including solenoid valves, contactors, signal lamps and small motors via mechanical contacts. Equipped with built-in freewheeling diode, polarity reversal protection and working status indicator, the module realizes electrical isolation between control side and load side to resist electromagnetic interference from inverters and servo drives. With slim compact design and convenient plug-and-play maintenance structure, it complies with CE, UL, CSA and RoHS standards, widely used in automated assembly lines, packaging machinery, machine tools, logistics conveying equipment and various factory automation control systems.

Main Functions
- Signal Amplification and Load Driving: Amplify weak current signals output by PLC to drive large-current loads that cannot be directly borne by PLC onboard ports.
- Galvanic Electrical Isolation: Isolate the PLC control circuit and field load circuit to prevent surge voltage, harmonic interference and back electromotive force from damaging the PLC main control board.
- Flexible Circuit Switching: The single-pole double-throw contact supports two-circuit switching, fulfilling start-stop, forward-reverse and other sequential control logic requirements.
- Real-time Working Status Prompt: The integrated LED light turns on when the coil is energized, helping technicians quickly check signal transmission and relay working conditions during debugging and troubleshooting.
- Rapid Fault Maintenance: The relay body can be directly pulled out from the base without removing wiring, greatly shortening equipment downtime during component replacement.
- Anti-wiring Error Protection: Built-in reverse polarity protection circuit effectively avoids coil burnout caused by positive and negative pole misconnection of DC power supply.
- Space-saving Cabinet Layout: Ultra-narrow 6.2 mm width greatly improves the layout density of multi-channel relay modules inside limited-space electrical cabinets.
- Adaptation to Long-term Continuous Operation: Fully sealed relay internal structure resists dust and slight oil mist erosion, suitable for 24-hour uninterrupted production operation.
Key Technical Features
- Ultra-slim body design maximizes the number of modules installed per unit rail length, perfectly applicable to compact small control cabinets.
- Fully sealed relay core prevents dust, moisture and corrosive gas intrusion, extending service life in complex industrial environments.
- High insulation strength meets international industrial safety standards, eliminating electric leakage risks between control and load loops.
- Built-in surge absorption element suppresses counter electromotive force generated by inductive loads such as solenoid valves, protecting front-end control devices.
- Screw terminals provide stable clamping force, free from loose contact faults triggered by equipment mechanical vibration.
- Unified universal base platform allows interchange of relays with different coil voltages for convenient equipment upgrading and spare parts management.
- Wide temperature tolerance ensures stable performance in both low-temperature workshops and high-temperature closed cabinets.
- Optimized internal mechanical structure boasts excellent vibration resistance, adapting to vibrating production equipment operating scenarios.
