Product Details
Configured for field signal interface and routing in Foxboro I/A Series system platforms, the Foxboro P0924JH (P0924JH Communication Terminal Assembly) provides direct physical/electrical execution. It terminates HART field input loops and connects directly to FBM214B and FBM216B Fieldbus Modules via screw terminals integrated into a polyamide housing.

Process Loop Signal Conditioning and Channel Isolation
The Foxboro P0924JH supports 4-20 mA HART loop protocol routing between hazardous or general field devices and the system interface backplane. The assembly maintains physical channel-to-channel isolation parameters to mitigate ground potential loops and cross-talk interference across multi-channel transmitter configurations. Signal paths pass directly to FBM214B and FBM216B HART input modules without active attenuation or impedance shifts.
Frequently Asked Questions
Q: What screw terminal torque rating should be applied during field wire termination?
A: Field wiring connection screws should be tightened to a maximum torque rating of 0.5 Nm to 0.6 Nm. Overtightening can compromise terminal block threads or damage conductor strands.
Q: Is external power required directly at the terminal assembly?
A: No, the P0924JH is a passive physical termination unit. Loop power for connected HART transmitters is sourced directly through the associated FBM214B or FBM216B module or an external loop power distribution block.
Field Installation Guidelines
Ensure all system backplane and field loop power feeds are isolated prior to landing conductors on the screw terminals. Strip conductor insulation to 6 mm to expose bare wire without leaving uninsulated metal outside the clamping housing.
All HART analog input wiring must utilize twisted-shielded cable pairs. Cable shields must be tied to a single, dedicated system chassis earth ground bar to avoid ground loops. Ensure NPT conduit hub fittings enter enclosures with a minimum 5-thread engagement to maintain environmental sealing standards.
