PLC-RSC
The Phoenix Contact PLC-RSC Series is part of the PLC-INTERFACE family, offering compact relay modules designed for efficient signal isolation and amplification in industrial automation systems. These DIN rail-mounted modules feature plug-in miniature relays with power contacts for reliable control applications.
Compact Design: At just 6.2 mm width, PLC-RSC modules maximize control cabinet space efficiency and enable high-density installations.
Versatile Contact Configurations: Available in single changeover (SPDT) and double changeover (DPDT) contact types to meet diverse switching requirements.
Wide Input Voltage Range: Compatible with 24 V DC, 230 V AC, and 220 V DC systems, providing flexible integration across different control architectures.
High Switching Capacity: Handles currents up to 6 A for both resistive and inductive loads, suitable for demanding industrial applications.
Integrated Protection: Built-in reverse polarity protection and freewheeling diodes ensure safe, reliable operation and extend component life.
Manual Operation Option: Select models include manual operation levers for simplified testing and maintenance without external actuation.
Applications: Ideal for signal isolation, load switching, and interface applications in PLCs, motor control centers, and automated manufacturing systems.
Notes
