User’s Manual Pub. 0300241-01 Rev. A

From the readings taken by the converter, the module returns an accurate temperature or

resistance to the controller user program through the microprocessor. The module uses

two bidirectional serial ports for communication, each using an optocoupler for isolation.

A third optocoupler is used to reset the microprocessor if the module detects a loss of

communication.
