Material Composition FR4 flame retardant PCB with acrylic conformal coating High precision 250 ohm metal film resistors for HART Optocoupler isolation array TVS surge suppression diodes Nylon flame retardant screw terminal block Tri-color per-channel LED indicators Metal rack fixing bracket and screws
Structural Features Horizontal rack-mounted FTA board. Front side is removable screw terminal block for field instrument wiring. Rear side multi-pin connector mates with HLAI IOP processor module. Each channel has independent LED indicator on front edge. Isolation barrier separates field circuit zone and logic connector zone. Fixing holes on both sides for rack installation.
Working Principle Field 4-20mA signal enters terminal block and passes through built-in 250 ohm HART resistor. Analog signal and superimposed HART digital signal go through galvanic isolation circuit. The signal is transmitted to HLAI IOP processor module via rear connector. The FTA monitors loop current continuously. When open circuit, short circuit or abnormal current is detected, fault signal is sent to IOP module and corresponding LED indicator lights fault state.
Installation Requirements Mount FTA board on DCS rack chassis and tighten fixing screws. Connect field shielded twisted pair instrument cable to corresponding terminal block. Connect rear connector cable to HLAI IOP processor module. Configure HART and channel parameters in Experion Control Builder. Power on rack and verify channel status and HART communication. Separate analog instrument cable from high voltage power cable.
Usage Notes Only shielded twisted pair cable is allowed for HART instrument wiring. Do not remove the built-in 250 ohm resistor for HART loop. The conformal coated board cannot be cleaned with solvent. Static protection must be taken during maintenance. Do not apply AC voltage to any input terminal.
