A.2 Functional Overview
The Model CM-C VSM Oven module (4101-200) is a temperature-control module that was
designed for the specific needs of the VSM Oven option. Figure A-1 shows the module and its
front panel.
The principle function of this module is to provide the appropriate current to a platinum heater
based on resistance feedback and temperature readings from a thermocouple and a thermistor.
The maximum heater output is 25 V rms at either 50 Hz or 60 Hz with synchronous current
readback detection. The temperature-control (PID) loop is closed digitally at about 10 Hz using a
16-bit current source. Other features include in-system programmable on-board flash memory for
program storage and a serial ROM for calibration and other configuration data.
