Process Input Units
Directly Input Four Temperature Sensors
• Up to four temperature sensor inputs can be
directly connected to a single Unit (input signal/
range shared by the four inputs)
• Models with isolation between channels
prevent unwanted current paths between
Temperature Sensor inputs.
• Measurement value alarm with hysteresis/ON delay
(two inputs per channel, one of which can be set as
a DO output from the Unit).
• High-resolution, high-speed 2 channel input models
provide configurable alarms and maintenance func-
tions
Converts the measured value of DC voltage/current signals, thermo-
couple or platinum-resistance thermometer inputs (up to 4 points) into
binary or BCD code, and stores in the allocated memory area every
cycle. The ladder program can be used to transfer the data to a speci-
fied words in data memory for use.
