LCU-FSD | SICK Dual Safety Relay Module with 2× 6 A Outputs

SICK · Relays, Contactors & Switches

Description  The SICK LCU-FSD is a dual safety relay module designed to provide monitored safety relay functions for machine and system safety circuits. The part functions as a captive contact safety interface with two 6 A safety relays on a compact DIN-rail mountable module. It is typically applied to industrial safety control circuits where reliable safety contact switching is required for emergency stops and guarded access detection.     Technical Specifications  Condition New/Never Used Surplus Brand SICK Part Number LCU-FSD Category Safety & Control Subcategory Safety Relays Functional Type Dual safety relay module Relay Outputs 2 safety relays Contact Rating 6 A per relay Mounting Type DIN-rail mount External Device Monitoring (EDM) Supported Input Voltage (commonly 24 V DC) typical for safety relays Status Indicators Relay activation and fault status LEDs Housing Material Industrial plastic/metal enclosure Operating Temperature Range Standard industrial range (e.g., 0-55 °C) Approvals Safety compliance (e.g., IEC/EN) Dimensions Compact DIN-rail module Weight ~0.51 lbs     Information About LCU-FSD The LCU-FSD is a safety relay module from SICK designed to interface safety devices such as emergency stops, light curtains, or guarded access switches with machine control systems. It consists of two captive contact safety relays with a combined capability to switch safety circuits up to 6 A each and supports external device monitoring. The module is built for industrial environments and is commonly DIN-rail mounted for easy integration into control cabinets. SICK safety relay modules like the LCU-FSD help ensure that safety circuits are evaluated and switched with reliable isolation and diagnostic capability. Key Features: Dual Safety Relays: includes two separate safety relay outputs for redundant safety control. Captive Contact Design: safety contacts return to a known status upon power loss or fault condition. DIN-Rail Mountable: designed for standard DIN-rail mounting inside control panels. 6 Amp Switching: each safety relay is rated to switch up to 6 A of load current. Machine Interface Module: suitable as an interface between safety devices and machine controllers. Safety Monitoring Support: supports external device monitoring (EDM) for increased safety diagnostics. Compact Design: space-efficient form factor for control cabinet installations. The LCU-FSD delivers the reliability and precision required for industrial safety circuit monitoring and control applications.
