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 and 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.
Table 10
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 the table.
IMPORTANT
The embedded analog I/O points are available on only the 1769-L24ER-QBFC1B
and 1769-L27ERM-QBFC1B controllers.
