BLASI – Relay 24VDC
BLASI – Relay 24 VDC, 3×CO, 10 A is a compact plug‑in or PCB‑type control blasi – relay used in BLASI automatic‑door panels, powered by a 24 V DC control supply. It has three changeover (3‑pole double‑throw, 3PDT) contacts rated for up to 10 A, making it suitable for switching auxiliary circuits such as indicators, small contactors, alarms or interlocks under the command of BLASI logic or safety modules. The relay typically plugs into a Series‑94 or similar socket on the BLASI DIN rail, so the panel wiring stays fixed while the relay module can be replaced during service. BLASI lists this as a “Relay 24 VDC, 3×CO, 10 A” in its spare‑parts range, treating it as a standard auxiliary control relay that fits BLASI‑panel layouts and control‑circuit schemes.
Product Details
BLASI – Relay 24 VDC, 3×CO, 10 A sits on the BLASI control‑board rail as an interface between low‑power DC signals (from time relays, safety boards or push‑buttons) and higher‑current auxiliary loads in swing, sliding or revolving‑door systems. When the BLASI panel supplies 24 V DC to the coil, all three changeover contacts switch simultaneously, allowing the relay to control three separate circuits—for example warning lights, a hold‑open magnet, and an interlock contact—all from one coil. This 3‑pole configuration simplifies the wiring diagram and keeps the BLASI panel tidy, while the 10 A contact rating at 230–250 V AC is sufficient for typical low‑power control‑circuit duties. The relay is usually mounted plug‑in fashion on a screw‑terminal socket such as Series‑94, so field wiring does not need to be touched during replacement.
Industry‑type 3‑pole, 24 V DC, 10 A plug‑in relays of this family commonly feature silver‑nickel contacts, an operating‑voltage range around 19–27 V DC, and a compact body (about 35–40 mm wide) that fits standard BLASI‑panel spacing. Many variants include a lockable test button and a mechanical flag that shows the relay state, helping technicians verify operation without opening the panel. These relays are intended for indoor control‑cabinet use, where temperature and vibration are moderate. By using BLASI – Relay 24 VDC, 3×CO, 10 A, service staff achieve a robust, modular way to drive multiple control circuits from a single 24 V DC coil, improving safety, maintainability and flexibility in BLASI‑based automatic‑door systems.
