Dison AMC169 REV A Vacuum Control Board PCB AMC170 110VAC 220VAC 1995

Dison AMC169 REV A Vacuum Control Board PCB AMC170 110VAC 220VAC 1995

The Dison AMC169 is a printed circuit board (PCB) designed for vacuum system control, designated PWB AMC169 REV A with an associated CCA AMC170 assembly designation. The board interfaces with both 110VAC and 220VAC power inputs and provides a dedicated overtemperature monitoring terminal, making it suitable for monitoring and control tasks in industrial vacuum or process automation equipment. The copyright date on the board is 1995, placing it in the mid-1990s generation of industrial control electronics.

Applications

The AMC169 is a control board designed for use within vacuum system assemblies — equipment such as industrial vacuum chambers, vacuum furnaces, or related automated process machinery. Control boards of this type manage input monitoring (including AC power presence and overtemperature conditions) and provide switching or interlock functions via optocoupler-isolated outputs, keeping control circuitry electrically isolated from higher-voltage AC lines. The dual 110VAC/220VAC terminal arrangement is typical of industrial control boards intended for international deployment or machinery wired for either mains standard. The overtemperature terminal suggests integration with a thermal sensor or thermostat in the parent system, providing a shutdown or alert signal when operating temperatures exceed a safe threshold. Boards of this generation from the mid-1990s are typically sought by technicians maintaining or repairing original equipment that relied on this specific PCB assembly.
