Description
WESTINGHOUSE 5X00241G01
The Eight (8) channel RTD module is used to convert inputs from Resistance Temperature
Detectors (RTDs) to digital data. The digitized data is transmitted to the Controller.

19A-2.3. Module Block Diagram and Field Connection Wiring
Diagram
The Ovation 8 Channel RTD module consists of two modules an electronics module
contains a logic printed circuit board (LIA) and a printed circuit board (FTD). The
electronics module is used in conjunction with a personalty module, which contains
a single printed circuit board (PTD). The block diagram for the 8 channel RTD module
is shown in Figure 19A-1.

Number of channels 8
Sampling rate 50 HZ mode: 16.67/sec. normally. In 3 wire mode, lead
resistance measurement occurs once every 6.45 sec.
during which the rate drops to 3/sec.
60 HZ mode: 20/sec. normally. In 3 wire mode, lead
resistance measurement occurs once every 6.45 sec.
during which the rate drops to 2/sec.
Self Calibration Mode: Occurs on demand only. The rate
drops to 1/sec. once during each self calibration cycle.
RTD ranges Refer to Table 19A-3.
