1-1 Features and Functions
This section introduces the features and primary functions of the CJ-series
CJ1W-AD04U and CJ1W-AD04U-SL Universal Input Units.
Four Input Channels The CJ1W-AD04U and CJ1W-AD04U-SL Universal Input Units are CJ-series
Special I/O Units with four input channels on each Unit. Each input channel
can be set independently to one of four input types: DC voltage, DC current,
thermocouple, or resistance thermometer.
Isolation between
Channels The input channels are isolated in the Universal Input Unit, so unwanted cur-
rent paths will not occur between thermocouple inputs or voltage inputs that
share the same power supply. Signal converters are not needed to prevent
interference between inputs.
