Allen-Bradley | 1734-OB8 | POINT I/O

Product Description: Allen-Bradley 1734-OB8

The Allen-Bradley 1734-OB8 is an 8-channel digital output module in the POINT I/O family, designed to provide sourcing (PNP) output signals to control external devices such as relays, indicators, solenoids, and motor starters. This module delivers reliable, space-saving output control for distributed and compact automation systems.

Key Features

• 8 sourcing (PNP) output channels
• Designed for use with DC loads (typically 24V DC)
• Individually switchable outputs
• Compact form factor ideal for distributed I/O
• LED indicators for per-channel output status
• Mounts on standard POINT I/O terminal bases
• Compatible with all POINT I/O backplane systems
