Universal Analog Input Module Wiring
The Universal Analog Input Module has eight inputs, which can include any combination of the following
input types: RTD, TC, Ohms, Millivolt, Volt, or Milliamp. Figure 31 shows wiring examples of each of the
analog input types. An example of wiring for eight TC inputs is given in Figure 33.
Specifications for this module and for other modules are given in the Specifications section of this manual.
Isolation
This module has eight inputs, which are isolated except for RTD current sources.
RTD Inputs
RTD inputs share current sources (two RTD inputs per
source), as shown in Figure 30, in Figure 31, and in
Figure 32.
For example, the current source for the RTD input at
channel one (terminals 1 and 2) is terminal 3 (I
RTD
1 &
2). This same current source (I
RTD
1 & 2) is also used
for an RTD input at channel two (terminals 4 and 5).
Figure 32 and Figure 35 show examples of RTD input
wiring (2-wire and 3-wire RTDs). Four-wire RTD
inputs are not available).
Figure 30 - RTD Inputs
OHMs Inputs
Ohms inputs are wired similar to 2-wire RTD inputs. That is, they require a current source, and thus must
use one of the I
RTD
current sources. Also, two terminals are jumpered together as they are for two-wire
RTD inputs.
Analog channels wired for Ohms inputs differ from RTD inputs in these aspects:
• Ohms inputs connect to variable resistance devices other than RTDs, and
• Ohms inputs are configured in Hybrid Control Designer as Ohms inputs, rather than as RTD inputs.
Examples of wiring for resistance inputs are given in Figure 34.
Shield Grounding
Shields must be grounded as described under Shield Grounding at the beginning of this section.
Hazardous voltages exist at terminal blocks.
• Using switches at field devices, disconnect the field wiring from power sources before servicing.
Failure to comply with these instructions could result in death or serious injury.
