Product Introduction

51304718-200 is a Honeywell HLAI/STI series basic high-level analog input field terminal board (FTA), compatible with DCS systems such as TDC 3000, TPS, UCN, and Experion PKS. As a signal transfer interface between field transmitters and main control analog input modules, it adopts screw-type terminal blocks and standard coated PCB, providing basic electrical isolation. It is a basic non-isolated / basic isolated entry-level model without redundant functions.

User and maintenance instructions Use

Installation: Fixed in a standard cabinet, reserve space for wiring and heat dissipation;

Wiring: Securely fasten the 50-pin cable, connect the wires on-site to the screw terminals, and tighten to prevent loosening;

Power-on and Debugging: After wiring is completed, start the DCS, check for no alarms, confirm the signal accuracy, and then put it into use. Maintenance

Environment: Keep the cabinet dry and clean, avoiding moisture and corrosive gases;

Inspection: Check the tightness of terminals and the integrity of cables every quarter, and tighten or replace them in time;

Cleaning: Use a dry soft cloth to remove dust; Do not allow liquid cleaners to come into contact with the circuit board and terminals;

Storage: Store spare parts in an anti-static bag, in a cool and dry place; Take precautions for anti-static during handling;

Disassembly: Non-professionals are not allowed to disassemble; Avoid damaging the circuit.
