S20330-SRS
Product Name
S20330-SRS Safety Relay Module (acts as a “fail-safe protective controller” in industrial machinery safety systems, specializing in monitoring safety devices and initiating emergency shutdowns to prevent accidents. With dual-channel verification and certified safety performance, it is widely used in industries such as automotive manufacturing, packaging, and material handling)
Product Description
The S20330-SRS is a high-reliability safety relay module designed to enforce safety functions in compliance with global safety standards. In an automotive assembly line, this module continuously monitors safety devices like light curtains, emergency stop buttons, and guard door interlocks. When a safety breach is detected—such as an operator reaching into a robotic workcell—the module immediately cuts power to hazardous machinery (e.g., robotic arms, conveyor motors) within milliseconds, preventing potential injuries. Its dual-channel design ensures that a single fault in one channel cannot compromise the safety function; both channels must confirm the hazard before triggering a shutdown, reducing the risk of false trips that could disrupt production.
In packaging machinery, the S20330-SRS module integrates with safety mats and two-hand control devices, ensuring that machines operate only when operators are in safe positions. It supports manual and automatic reset modes, allowing restart only after the safety hazard is resolved and the reset conditio
