Televac® MC300 Vacuum Controller

The MC300 will be discontinued on September 30, 2022.

The direct replacement vacuum controller is the MX200 Vacuum Controller.

Part Numbers: 2-4502-301, 2-4502-302, 2-4502-303, 2-4502-304, 2-4502-305, 2-4502-306, 2-4503-401, 2-4503-402


Compatible With: 1E Piezo Diaphragm, 1F Piezo Diaphragm, 2A Thermocouple, 4A Convection, 7B Cold Cathode, 7E Cold Cathode, 7F Cold Cathode, 7FC Cold Cathode, 7FCS Cold Cathode, 3F Hot Ion


Features and Benefits:

  • Competitively priced
  • Built-in self-diagnostics
  • Easy to read, large LED display
  • Four process relays with individually assignable set points
  • Analog outputs for each sensor
  • Excellent customer support

The Televac® MC300 vacuum controller controls up to two Televac® thermocouple gauges or convection gauges and an optional cold cathode gauge or mini BA hot ion high vacuum gauge. It features a 0 to 10 V DC analog output for each vacuum gauge, 4 relay set points for process control, and large, bright LED display, making it easy to read from a distance.

Note: sensors and cables are not included and must be ordered separately.
