Technical Specifications Multi‑channel pulse signal input and isolated pulse output. Auxiliary working power 24 V DC, typical power consumption 6.3 W. Operating temperature ‑10 ℃ to +55 ℃, storage temperature ‑40 ℃ to +85 ℃, non‑condensing relative humidity 5%‑95%. Conformal coated printed circuit board, isolation voltage 2500 V AC.
Functional Features Receives trigger pulse signals from main control board. Realizes high‑voltage galvanic isolation via on‑board pulse transformers. Outputs driving pulses to thyristor or IGCT power components. On‑board LED indicates pulse channel operating status. Built‑in hardware self‑diagnosis for pulse circuit abnormality. Conformal coating provides moisture‑proof and dust‑proof protection.
Application Scenarios Core replacement spare‑part for ABB medium‑voltage drives and generator excitation systems. Widely used in power plants, metallurgy and heavy‑industry automation sites for equipment overhaul and spare‑part replacement.
Performance Parameters Accurate pulse phase and timing output meets power‑device triggering requirements. High‑voltage isolation effectively suppresses electromagnetic interference. Self‑diagnosis rapidly detects pulse channel loss and circuit faults.
Material Composition Multilayer glass‑fiber epoxy printed circuit board. Pulse transformer assemblies, signal conditioning components. Conformal protective coating. Back‑plane plug‑in connectors and high‑voltage pulse output terminals.
Structural Characteristics Standard plug‑in circuit board matching cabinet rack slot. Board edge equipped with back‑plane bus connector and pulse output wiring terminals. Reserved mechanical fixing holes. Weight approximately 0.65 kilogram.
Working Principle After power‑on, the board completes hardware self‑check. Trigger pulse signals from main controller enter the board through back‑plane connector. Signals pass through pulse transformer for high‑voltage isolation.
Installation Requirements Cut off all control power and high‑voltage power of cabinet before replacement. Insert YPC104B YT204001‑BT into designated slot and tighten fixing screws. Confirm back‑plane connector is fully engaged.
Usage Notes Apply anti‑static wrist strap during disassembly and assembly. Do not scratch conformal coating surface. Hot‑plug operation under powered state is strictly forbidden.
