3.1 Input Functions
The DTM series allows the setting of input channel type as thermocouple pair, resistance temperature
detection, analog voltage input, or analog current input.
3.1.1 Input Function Settings
Hardware connection: (as shown in the following figure and table)
A. Thermocouple pair (TC): Connect TC-, TC+ to the corresponding contacts
B. Resistance temperature sensor(RTD): Three-wire connection method: Connect the RTD to the input
terminal corresponding to temperature control
C. Analog voltage (V): Connect the analog voltage V+, V- to the corresponding contacts
D. Analog current (mA): Connect the analog current I+, I- to the corresponding contacts
