Allen-Bradley 1734-FPD Field Potential Distributor

Configured for power distribution segmentation in the POINT I/O backplane network, the Allen-Bradley 1734-FPD (1734-FPD Field Potential Distributor) provides direct electrical separation and field power routing between adjacent I/O sections. The unit is installed between POINT I/O modules to distribute AC or DC field power while maintaining POINTBus current pass-through operation across the system architecture.

Hardware Specifications

Backplane Communication and I/O Segmentation

Within the POINT I/O architecture, the 1734-FPD separates field-side power distribution while allowing POINTBus communication continuity through the backplane. This arrangement permits different voltage groups to be supplied across adjacent I/O sections without interrupting the bus structure. The module functions as a power distribution boundary rather than an active communication processor and does not introduce status indication or local control logic.

Frequently Asked Questions

Q: Does the 1734-FPD interrupt POINTBus communication between modules?
A: No. The module passes POINTBus current through the assembly while providing field power distribution and isolation functions between I/O groups.

Q: Can the 1734-FPD be installed anywhere within a POINT I/O assembly?
A: The module is designed to be installed between POINT I/O modules where field power segmentation is required within the system.

Q: Does the 1734-FPD support hot-swap replacement?
A: The provided documentation does not specify hot-swap capability. Module replacement should follow system shutdown and site maintenance procedures unless otherwise stated in the applicable POINT I/O installation manual.

Field Installation Guidelines

• Mount the distributor securely on a properly grounded DIN rail before wiring field power conductors.

• Apply the specified terminal base tightening torque of 0.6 Nm to prevent loose electrical connections or terminal damage.

• Verify field supply voltage compatibility before energizing the module.

• Maintain separation between power wiring and communication wiring according to plant electrical installation practices.

• Follow Category 1 wiring requirements for power ports.

• Ensure protective earth grounding and cable routing practices comply with applicable electrical codes and site standards.

• Confirm conductor sizing is appropriate for the maximum input current rating of 10 A.

• De-energize associated field circuits before installation or removal of wiring connections.
