Foxboro P0918HU Industrial Power Module

The Foxboro P0918HU, also cataloged as the P0918HU Industrial Power Module, operates as a dedicated hardware component for regulated DC power distribution within Foxboro I/A Series system platforms. It converts 90-264 VAC AC line power into a regulated 24 VDC output at up to 100 W power output, supplying bus voltage directly to control system racks, active I/O modules, and field devices.

4-20 mA HART Loop Protocol & Channel Isolation

The P0918HU power supply module delivers clean 24 VDC loop power across backplane buses to energize transmitter field loops without introducing high-frequency switching ripple. Internal input-to-output galvanic isolation prevents line-side noise and common-mode transients from reaching sensitive I/O analog-to-digital processing stages. By maintaining stable voltage delivery across field wiring runs, the unit preserves signal integrity for 4-20 mA HART loop protocol telemetry, ensuring channel-to-channel isolation barriers and internal cold junction compensation (CJC) circuits remain free from power-induced ground loop interference.

Frequently Asked Questions

Q: Can the P0918HU power module be installed on a standard DIN rail?

A: Yes. The unit features an integrated rear DIN rail locking clip designed to mount onto standard industrial DIN rail channels inside field enclosures.

Q: What protective features prevent hardware failure during AC line surges?

A: The module incorporates internal surge protection circuitry along with over-voltage and over-current protection stages that limit output delivery during electrical faults.

Q: Is the 100 W power output sufficient to run multiple high-density I/O racks?

A: The total current draw of connected devices must be calculated prior to installation. If total power consumption exceeds 100 W at 24 VDC, additional power modules must be installed across the backplane structure.

Field Installation Guidelines

Mount the P0918HU vertically on a DIN rail, securing adequate free air space above and below the housing to facilitate natural convection cooling across the internal heat sinks. Connect incoming 90-264 VAC lines to the designated input terminals, ensuring the protective earth conductor is bonded directly to the main cabinet ground bar. Keep 24 VDC output wiring physically segregated from AC line power runs inside wire ducts to eliminate electromagnetic coupling. Verify that line fusing matches the rated module input specifications before applying utility power.
