Allen-Bradley 1734D-IB8XOW8S POINT Block I/O Module

Configured for 24 VDC discrete signal input sensing and relay output switching in DeviceNet control networks, the Allen-Bradley 1734D-IB8XOW8S (1734D-IB8XOW8S Combination Block Module) provides direct physical/electrical execution.

Hardware Specifications

DeviceNet Protocol and I/O Density Scaling

• Integrated DeviceNet transceiver enables deterministic message execution and direct connection to industrial fieldbus networks without external network interface adapters.
• Combination architecture integrates 8 discrete 24 VDC sink inputs and 8 electromechanical relay outputs within a single hardware block to scale panel mounting density.
• Onboard processing maintains firmware compatibility across standard scanner backplane communication velocity profiles to prevent polling latency.

Frequently Asked Questions

Q: How are field wiring conductors attached to the 1734D-IB8XOW8S module?

A: Connections are secured using integrated spring clamp terminals for tool-free, vibration-resistant conductor termination.

Q: What power source supplies the primary network and module logic?

A: Internal processing circuitry and network communications are powered directly via the 24 VDC DeviceNet bus connection.

Field Installation Guidelines

• Mount the block assembly firmly onto a grounded 35 mm DIN rail inside an IP54 or NEMA rated panel enclosure.
• Strip field wiring to specified length and insert directly into spring terminals, verifying physical retention of each conductor.
• Ground the DeviceNet trunk shield drain wire at a single reference point to eliminate network communication ground loops.
• Separate high-voltage AC load relay wiring from low-voltage 24 VDC network and signal conduits to prevent electrical noise coupling.
