Use I/O Modules with CompactLogix 5370 L2 Controllers Chapter 8
Embedded Analog I/O Points
The 1769-L24ER-QBFC1B and 1769-L27ERM-QBFC1B controllers
support four embedded universal analog inputs that can function as
differential or single-ended inputs. This capability applies only if you do not
use RTDs. If you use RTDs in your system, you can use up to two RTDs or a
combination of one RTD and two universal analog inputs. The
1769-L24ER-QBFC1B and 1769-L27ERM-QBFC1B controllers also
support two embedded standard analog outputs that can function as single-
ended outputs. The inputs and outputs are considered channels. Each channel
configuration offers multiple configuration options.
Tab le 11
lists the available embedded analog input channel types and ranges for
the channel type. The configuration choices are made on the Input
Configuration tab of the Module Properties dialog box, as shown in Tab le 1 1
.
IMPORTANT The embedded analog I/O points are available on only the
1769-L24ER-QBFC1B and 1769-L27ERM-QBFC1B controllers.
