Product Details
Configured for high-density power conversion in Foxboro I/A Series control racks, the Foxboro P0700HU, also cataloged as the P0700HU Power Supply Module, provides direct physical/electrical execution. This assembly regulates incoming utility power into conditioned backplane DC voltages, supplying isolated logic power to fieldbus modules and processing units across the system enclosure.

DCS Process Control and Power Rail Isolation
The Foxboro P0700HU power supply module incorporates high-frequency switching technology and internal isolation transformers to shield system logic from AC line surges and ground loops. Designed to maintain stable output power across 4-20 mA HART loop protocol field networks and DCS I/O backplanes, the unit regulates voltage rails under fluctuating line conditions. Galvanic isolation between primary line inputs and system backplane outputs ensures electrical noise suppression and prevents common-mode voltage field spikes from damaging delicate controller architecture.
Frequently Asked Questions
Q: Does the Foxboro P0700HU support hot-swappable installation in redundant power configurations?
A: Yes, in dual-redundant baseplate setups, a single P0700HU module can be removed and replaced without interrupting power to the operational control modules on the active backplane.
Q: How does the internal circuit protection handle field-side short circuits or line over-voltage events?
A: The module features active foldback current limiting and over-voltage clamping circuitry that temporarily disables the output rail during fault conditions to protect downstream I/O logic.
Field Installation Guidelines
- Inspect the module chassis and rear connector pins for physical damage before inserting it into the rack enclosure.
- Align the module card guide with the baseplate mounting slot and push firmly until the locking latch clicks into place.
- Verify that the primary power source circuit breaker is open before connecting power input leads to the baseplate terminal strip.
- Connect the main protective earth (PE) ground wire directly to the cabinet ground bar to ensure proper EMI filtering performance.
