ABB 1SNA645005R0700 Industrial Safety Relay Module

ABB 1SNA645005R0700 is an interface relay module in the R600 family designed for DIN-rail mounting. It provides one Form C (SPDT) contact rated up to 6 A at 250 VAC and is driven by a 24 V AC/DC coil, drawing about 10 mA (roughly 0.24 W) when energized; an LED indicator shows the coil status. The module uses screw terminals for connections, is intended for horizontal DIN-rail mounting, and comes in an IP20/NEMA 1 enclosure suitable for standard industrial cabinets. Its compact footprint is about 67.5 mm high, 6 mm wide, and 70 mm deep, and it operates over a temperature range of -20 to 70 C. Typical uses include interfacing control or safety circuits to PLCs or safety controllers, alarms, or downstream actuators in automation systems.
