Description
The WAGO 753 series pluggable fail-safe/safety DC digital input slice module is designed for high safety applications, meeting SIL3/Cat4/Ple or SIL2/Cat2/Pld standards. It features four digital inputs with test pulse capability, operates on a 24V DC supply, and supports PROFIsafe communication. The module is powered by a 5V DC system supply, uses spring CAGE CLAMP connections, and mounts on a DIN-35 rail with a 12mm width. It is rated for ambient temperatures from 0°C to +55°C and complies with multiple IEC and EN safety standards. This module replaces the obsolete 753-661/000-003 component and is equivalent to the 753661000004 model.
