WRC4-OB5S - DC Output Module

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

Application Notes

• Do not install or remove modules in live (electrically hot) circuits. High voltage may be present.
• Output connections are polarized.
• An externally located commutating diode must be installed across inductive loads.
