Overview

Module Operation

As shown in the block diagram below, each input channel of the module
consists of an RTD/resistance connection that accepts excitation current; a
sense connection that detects lead wire resistance; and a return
connection. The signals are multiplexed to an A/D converter that reads
the RTD or resistance value and the lead wire resistance.

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.

Module Field Calibration

The input module performs autocalibration when a channel is initially
enabled. Autocalibration compensates for offset and gain drift of the A/D
converter caused by temperature change within the module. An internal,
high-precision, low drift voltage and system ground reference is used for
this purpose. In addition, you can program the module to perform a
calibration cycle once every 5 minutes. See Selecting Enable/Disable
Cyclic Autocalibration (Word 6, Bit 0) on page 4-19 for information on
configuring the module to perform periodic calibration.
