The WRC4-OB5S is a DC Output Module. One in a series of solid-state relays commonly used in industrial applications. The WRC4 package offers the following advantages:

  • Status LED is more easily visible
  • Fuse can be tested and replaced without removing the modules
  • Fuse is a popular CE-rated fuse
  • Popular Euro-style fuse has multiple sources
  • Matches the industry de facto standard footprint
  • Low height convenient for mounting
  • Compact footprint continues to save space
  • Compatible with WRC’s line of SmartMux and data aquisition cards
  • UL and CE marks standard
  • 5, 15 and 24 volt logic available
  • Proven reliable circuitry
