Product Details
The Foxboro P0926HM, also cataloged as the P0926HM Horizontal Baseplate Time Stroke Module, operates as a dedicated hardware component for time strobe signal synchronization and power distribution within Foxboro I/A Series platforms. It accommodates up to four Fieldbus Modules (FBMs) across a horizontal mounting format to coordinate real-time control actions and bus communications.

Process Loop Signal Conditioning and Channel Isolation
The Foxboro P0926HM utilizes dedicated internal isolation pathways to shield high-frequency time strobe pulses from field-side loop interference. By maintaining clean channel-to-channel isolation across the 24 VDC power rail and backplane signal traces, the baseplate prevents common-mode noise propagation, preserving 4-20 mA HART loop protocol signal integrity across all four attached FBM slots.
Frequently Asked Questions
Q: How is power redundancy implemented across the four module slots on the P0926HM?
A: The baseplate contains dual independent 24 VDC power distribution tracks with integrated diode decoupling, enabling uninterrupted module execution during a single power supply failure.
Q: Can Fieldbus Modules installed on the P0926HM baseplate be live-swapped during active system processing?
A: Yes, the baseplate supports hot-swapping of compatible FBMs, permitting module replacement without interrupting time strobe signals or communication traffic on adjacent slots.
Field Installation Guidelines
Secure the baseplate horizontally onto the cabinet mounting surface using appropriate fasteners. Ensure the chassis ground connection makes solid metal-to-metal contact with an unpainted, conductive backpanel to establish a low-impedance path to earth ground. Maintain at least 50 mm of vertical clearance above and below the assembly for unimpeded natural thermal convection.
Connect redundant 24 VDC power lines using separate, fused power feeds. Run all field communications and time strobe wiring using shielded twisted-pair cables, bonding the shield drain wires to a central grounding bar. When routing cables through panel entries, ensure standard NPT fittings achieve at least 5 full threads of engagement to preserve cabinet enclosure integrity.
