The SICK LY3-EMSS300 is a modular safety relay designed to monitor emergency stop circuits and other safety functions as defined by machinery safety standards (e.g., ISO 13849-1, IEC 62061). It is a core component in building safety control systems for industrial machinery, ensuring the safe shutdown of equipment when a hazard is detected.
Number of Channels: Typically 1 or 2 (refer to datasheet for this specific model)
Contact Configuration: Force-guided relays (e.g., 2 NO / 2 NC)
Reset Mode: Manual reset (via a separate reset button/input)
Supply Voltage: 24V DC (standard industrial control voltage)
Mounting: Standard 35mm DIN rail
the SICK LY3-EMSS300 is a reliable, certified, and essential component for implementing safety-critical shutdown functions on industrial machinery. It translates the activation of a basic safety device like an E-stop button into a guaranteed, fault-tolerant safety response.
