Product Manual：

Ansaldo P697 T is a dedicated PCB board for dual SCR triggering of transmission devices, commonly used for replacing spare parts in speed control equipment.
Dual independent trigger circuit, controlling the operation of two groups of thyristors
Signal electrical isolation, blocking interference and damaging triggering components
Equipped with a built-in voltage regulator circuit to adapt to on-site voltage fluctuations
Standard card insertion style, convenient rack insertion and replacement
Work indicator light, visually determine the triggering circuit status
Three proof coating for the whole board, dustproof and moisture-proof, suitable for industrial and mining scenes
Surface mount components, resistant to equipment vibration and less prone to failure
Wide temperature device, stable output pulse of high and low temperature cabinets

Reserve test points for easy maintenance, measurement, and triggering of waveforms
Precise wiring ensures precise timing of triggering pulses
Adjustable potentiometer, on-site calibration triggers phase adjustment
Cooperate with the main control board to achieve rectification and voltage regulation control
Built in overcurrent protection, cuts off trigger output in case of abnormality
Suitable for Ansaldo old-fashioned DC speed regulation machine
Factory aging testing, low failure rate during long-term operation
ending
