Product Description

Home > Products > Phoenix Contact > PLC Interface Modules Need Phoenix Contact 2979511? Interface relay module for PLC interface, industrial control systems. Supplied with full traceability and documentation.... Price & Availability This module features a 24V DC coil with a nominal input current of 9 mA, making it highly efficient for PLC and electronic control applications. The relay output is a single-pole changeover contact (1PDT) rated at 6A/250V AC, providing reliable switching for a wide range of loads. The module is housed in a compact 14mm wide terminal block housing with screw connection technology, ensuring secure and tool-friendly wiring. This plug-in relay module is part of the PLC-INTERFACE series, which combines a terminal block and a plug-in miniature relay in one unit. The 2979511 is designed for DIN rail mounting (35mm) and features a push-in actuator for manual operation, making commissioning and testing easier. The module includes a freewheeling diode for coil overvoltage protection, extending the relay's lifespan. With an ambient operating temperature range of -40°C to +60°C, it is suitable for demanding industrial environments. The PLC-BSC- 24DC/21 is a versatile solution for signal isolation, signal amplification, and potential matching in control cabinets. Its screw connection technology ensures vibration-resistant and maintenance-friendly wiring, while the integrated LED indicator provides clear visual status feedback. This module is a direct replacement for older PLC-INTERFACE versions and is fully compatible with Phoenix Contact's extensive range of accessories, including relay holders and marking tags. The Phoenix Contact 2979511 is a PLC-BSC- 24DC/21 interface relay module designed for seamless integration into industrial control systems. Basic Product Information 24V DC coil with integrated freewheeling diode 1PDT relay output rated at 6A/250V AC LED status indicator for coil voltage Manual push-in actuator for testing DIN rail mounting (35mm) per EN 60715 Compact 14mm housing with screw connection Technical Specifications Version & Model Difference The 2979511 (PLC-BSC- 24DC/21) is the current version of the PLC-INTERFACE series. Earlier versions (e.g., PLC-RSC- 24DC/21) used a different housing design with a separate relay and base, while the PLC-BSC series integrates the relay into a single unit. The PLC-BSC series offers a narrower width (14mm vs. 16mm) and improved LED visibility. Compared to the PLC-OSC series, the PLC-BSC has a higher switching capacity (6A vs. 3A) and includes a manual actuator as standard. The 2979511 is also available in a variant with push-in connection (PLC-BSC- 24DC/21-21) for tool-less wiring. Application Scenarios Can the 2979511 switch AC loads? Yes, the relay contact is rated for 250V AC/DC and can switch up to 6A. The maximum switching capacity is 1500 VA for AC loads and 90 W for DC loads, making it suitable for most industrial applications. What is the difference between PLC-BSC and PLC-RSC series? The PLC-BSC series (like 2979511) has an integrated relay and terminal block in a single 14mm housing, while the PLC-RSC series uses a separate relay and base. The PLC-BSC offers a narrower width and a manual actuator, but the PLC-RSC allows for easy relay replacement without disconnecting wiring. Is the 2979511 suitable for DIN rail mounting? Yes, it mounts on a 35mm DIN rail according to EN 60715. The module snaps onto the rail without tools and can be removed using a screwdriver, making installation and maintenance quick and easy. What is the coil voltage and current of the Phoenix Contact 2979511? The coil voltage is 24V DC with a nominal input current of 9 mA. This low current makes it suitable for direct connection to PLC outputs without additional power amplification.
