PLC-RSC- 24DC/21 ATEX - Relay Module

PLC-INTERFACE, consisting of DIN rail-mountable basic terminal block with screw connection and plug-in miniature relay with power contact, 1 changeover contact, input voltage: 24 V DC, UL/cUL: approved for use in Ex Zone Class I, Div. 2 and ATEX (Zone 2)

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.
