BLASI – Relais PLC-RSC-24DC/21 VO3
BLASI – Relais PLC‑RSC‑24DC/21 VO3 is a Phoenix‑Contact‑type PLC‑interface relay module used in BLASI control cabinets for automatic doors and barriers. It runs on 24 V DC and includes a pluggable relay with at least one changeover contact, mounted on a compact DIN‑rail terminal block for easy installation in crowded panels. This BLASI – Relais PLC‑RSC‑24DC/21 VO3 is designed for universal control duties such as switching small loads, providing isolation between the BLASI control board and field devices, and supporting safety and logic interlocks. Its 24 V DC coil and standard screw terminals make it simple to integrate into typical BLASI DC‑control wiring schemes.
Product Details
BLASI – Relais PLC‑RSC‑24DC/21 VO3 is part of the PLC‑INTERFACE series of relay modules made by Phoenix Contact and used as a signal‑and‑power interface in BLASI automatic door and barrier control systems. The relay is powered from a 24 V DC control supply and operates with a 100% duty cycle, so it can remain energized continuously without overheating, which is important for long‑term PLC or controller outputs. The module combines a basic terminal block (PLC‑BSC‑style) with a pluggable miniature relay, allowing the relay to be replaced without rewiring the whole terminal strip.
The relay contact side typically includes one or more changeover contacts rated for standard industrial voltages and currents, enabling it to safely switch indicator lights, small contactors, valve solenoids, or auxiliary control circuits. The module is built for DIN rail NS 35/7.5 mounting, so several PLC‑RSC‑type relays can be arranged side‑by‑side in the BLASI cabinet, which simplifies control‑panel layout and standardization. By using the BLASI – Relais PLC‑RSC‑24DC/21 VO3, maintenance teams gain a compact, modular relay solution that supports isolation, load switching, and flexible logic expansion while keeping wiring neat and reliable in BLASI automatic door and barrier systems.
