2.5 Analog Outputs
Each sensor on the MC300 ships with two different analog output formats for ease of use by the
customer. Consult the appropriate section below to learn more about each sensor output. The MC300
will return to its normal operating mode after the fourth relay has been set up or 60 seconds have
elapsed since the last button press. Changes are stored after the complete set up of an individual
relay channel. These set up parameters are stored in non-volatile memory and are not lost during
power outages.
2.5.1 2A Thermocouple Sensor
The 2A Thermocouple sensor has two analog output formats. The Traditional Output option mimics
the output of the raw signal from the 2A sensor. The voltage can be converted to a pressure by using
a linear interpolation table.
The Linear Output option provides a linear signal from .001 Torr to 1 Torr. The voltage can be converted
to a pressure via an equation.
