Product Description
The Allen-Bradley 1734D-IB8XOW8S POINT I/O module, part of the POINTBlock series, offers DC power, 8 inputs, and 8 relay outputs with communication speeds of 125, 250, or 500 KB/s. This DIN-rail mounted module, consuming 8.2 Watts (2 Watts dissipation) at 24V DC, integrates into networks via a communication interface supporting one to eight points per module. It features a built-in power supply converting 24V DC to 5V DC, a non-isolated DeviceNet interface, removable terminations, a POINTBus expansion port, and consumer/produce technology for Logix control communication. Ideal for cost-sensitive and flexible applications, the 1734D-IB8XOW8S leverages Rockwell Automation's NetLinx architecture (Ethernet/IP, ControlNet, DeviceNet) and provides universal configuration and diagnostics for easy integration into diverse automation systems.
Is Your Device Showing These Signs?
The Allen Bradley 1734D-IB8XOW8S POINT I/O module commonly experiences field wiring failures, necessitating terminal block replacement or rewiring. Diagnostic LEDs often indicate issues stemming from sensor or actuator malfunctions, requiring troubleshooting of connected devices and signal integrity verification. Communication errors on the POINTBus backplane demand inspection of the communication adapter, power supply, and adjacent modules for proper configuration and functionality. Module failures require firmware updates or complete unit replacement to restore proper operation within the distributed I/O system. Resolve ground loops and electrical noise affecting signal quality through proper shielding and grounding techniques.

Our Repair Process for the
1734D-IB8XOW8S
Our repair process for the Allen Bradley 1734D-IB8XOW8S POINT I/O module begins with addressing field wiring failures by replacing the terminal block or performing necessary rewiring. Next, diagnostic LEDs are used to identify sensor or actuator malfunctions, which are resolved through troubleshooting of connected devices and verification of signal integrity. Communication errors on the POINTBus backplane are corrected by inspecting the communication adapter, power supply, and adjacent modules to ensure proper configuration and functionality. Module failures are rectified through firmware updates or complete unit replacement to restore proper operation. Finally, ground loops and electrical noise affecting signal quality are eliminated through the implementation of proper shielding and grounding techniques.
