Allen-Bradley | 1734-OW4 |POINT I/O

Product Description: Allen-Bradley 1734-OW4

The Allen-Bradley 1734-OW4 is a 4-channel relay output module designed for use in the POINT I/O system. It features electromechanical relays that allow for switching AC or DC loads independently. With individually isolated channels, the module supports a wide variety of discrete control applications, making it ideal for interfacing with solenoids, contactors, lamps, and other field actuators.

Key Features

• 4 individually isolated relay output channels
• Supports switching of both AC and DC loads
• Electromechanical relays provide physical contact switching
• Each channel can switch independently
• LED indicators for channel status monitoring
• Compatible with standard POINT I/O terminal bases
• DIN rail mounting for compact and modular design
