描述

The RF1V-4A2B-D24 is a 4-pole force-guided safety relay manufactured by IDEC, designed for flexible construction of safety circuits in industrial automation environments. It features a 4NO-2NC (4 normally open, 2 normally closed) contact configuration with a 24V DC rated coil voltage and AgSnO2 (gold-flashed) contact material rated for 6A at 250V AC or 6A at 30V DC resistive loads. The relay delivers a fast response time of 8 ms maximum and an operating time of 20 ms maximum, with a release time of 2 ms maximum, ensuring rapid load disconnection for safety-critical applications. It exhibits high shock resistance rated at 200 m/s² (150 m/s² when mounted on DIN rail socket) and operates reliably across -40°C to +85°C with 10 to 55 Hz vibration resistance at 0.75 mm amplitude. The compact 4-pole design measures 13W × 40D × 24H mm and weighs approximately 20 g, enabling space-efficient integration into control boards. This relay complies with international safety standards including EN50205 Type A (TÜV approved), UL508, and CSA C22.2 No. 14, making it ideal for machine tool controls, safety interlocks, and vibration-prone industrial environments.
