Televac® MC300 Vacuum Controller

Discontinued: The direct replacement 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.

The MC300 has four relay set points. Individual relay status LEDs are displayed on the front panel. The heavy duty relays have a SPDT (1 Form C) contact and are rated for 24 V DC. They have a maximum current rating of 8 A at 250 V AC or 5 A at 30 V DC. The data sheet can be found at http://www.omron.com/ecb/products/pdf/en-g6rn.pdf.

The MC300 is sold in configurations containing high vacuum sensors (cold cathode or hot ion). The high vacuum sensor is controlled automatically by the low vacuum sensor connected to station 1. It is switched on when station 1 reads below 10 microns (10 mTorr or 0.010 Torr). When operating high vacuum sensors, it is recommended that the channel 3 high vacuum sensor and channel 1 low vacuum sensor be located near one another on the same manifold.

Housing Cold rolled steel
