Terminal Arrangement
DRT1-TS04T
Note Do not touch or remove the Cold Junction Compensator.
DRT1-TS04P
Wiring Connect the inputs to the Temperature Input Terminal’s terminal block as
shown in the following diagram, depending on whether thermocouple inputs
or resistance temperature sensor inputs are used.
Temperature Conversion
Data for the DRT1-TS04T
and DRT1-TS04P
Data that is input is converted to binary data (4-digit hexadecimal) and the
Master is notified. If the converted data is a negative number, it is expressed
as a two’s complement.
