Datasheet Summary
Powered by GS/AI

The 2447935-2 is a single-function safety relay designed to interface with two OSSD devices, such as safety light curtains, providing control of external contactors with an integrated EDM feedback input and one system status PNP output. It features forced-guided relay outputs rated for 6 A at 250 VAC/125 VDC, a response time of ≤ 20 ms, and operates on a 24 VDC power supply (±20%). The unit includes input, output, and fail status LEDs for diagnostics, and supports selectable automatic or manual restart. It is mounted on a DIN rail, complies with EN 50022-35, and has IP20 housing and IP2X terminal block protection. The dimensions are 99 mm height, 22.5 mm width, and 114 mm depth. It meets safety level Type 4, SIL 3, PL e, and Cat. 4 per EN 61131-2, with CE approval. Connection is via screw clamp. Operating temperature ranges from -30 °C to +55 °C.
