17.6.5 Thermistor Input Interface
By connecting the remote I/O unit with thermistor, up to 12 points of thermistor input are available.
For details on units with the thermistor input function, refer to "4.9 Remote I/O Unit".
Up to 12 points of the thermistor are detected in the ascending order of the channel No. and station No. of the remote I/O
unit. The file registers outputting temperature information are assigned inputs (thermistor input n (TIn)) but are not assigned
to the 13th or later thermistor input. The relationship between thermistor inputs and file registers is as follows:
[PLC input signals]
Through the interface you can read the temperature sensed by a thermistor connected to the designated connector of
thermistor input-equipped remote I/O unit.

TI0 ZR13028 The thermistor voltage acquired with the thermistor input-equipped re-
mote I/O unit is input after converted to a temperature value per PLC me-
dium-speed cycle.
One station of remote I/O has 4 thermistor inputs, thus 4 PLC medium-
speed cycles are required for the inputs of one station.
