Machine Support Control Board 100A

Main features of the controller:

• STM8 industrial microcontroller for main control.
• Strong and weak electrical interface via fiber optic isolator for safer operation.
• Power cable and foot switch cable with screwless quick-connect terminals, more convenient and reliable.
• Time and current input with high-precision single-digit potentiometer, ensuring reliable and convenient input.
• Power, status, foot switch, and trigger indicators, with clear visibility of working status.
• Reliable zero-crossing detection circuit design for accurate SCR phase switching.
• The controller is compatible with SCR 100A.
• Digital control interface, displaying the set time and current.
• Different input times 1-50, cycle unit (1 cycle is 20ms), input current (30-99%).
• Digital display of time and current, time range 1-50 cycles, one cycle is 20 milliseconds, current range 30-99%.
• Screwless quick-connect terminals, press the upper protrusion by hand, insert the wire and release, the wire can be fixed tightly, very convenient.
• The strong and weak electrical interface is isolated via fiber optic isolator for safer operation.
• Compatible with SCR 100A.
• Uses industrial microcontroller for reliable zero-crossing detection design, stable and reliable performance.
• Time current regulator.
• Indicator on the board, with clear working status.

Fault description: Time or current setting is not adjustable, the number does not change.
