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 modules are engineered for DIN rail mounting and feature plug-in miniature relays with power contacts, ensuring reliable performance in various control applications.
Key Features:
Compact Design: With a slim 6.2 mm width, the PLC-RSC modules save space in control cabinets, allowing for high-density installations.
Versatile Contact Configurations: Available with different contact types, including single changeover (SPDT) and double changeover (DPDT) contacts, to suit diverse application needs.
Wide Input Voltage Range: Models support various input voltages, such as 24 V DC, 230 V AC, and 220 V DC, providing flexibility for integration into different control systems.
High Switching Capacity: Designed to handle currents up to 6 A, these modules are suitable for switching both resistive and inductive loads.
Integrated Protective Features: Equipped with reverse polarity protection and freewheeling diodes, the PLC-RSC modules ensure safe and reliable operation.
Manual Operation Option: Certain models include a manual operation lever, facilitating easy testing and maintenance without the need for external actuation.
