TERMINAL LAYOUT AND WIRING
Wiring graph for instruments with dimension A, A2, B, C, C3, E or F
The compensation wires for different kinds of thermocouple are different, and should be directly connect
to the terminals. Connecting the common wire between the compensation wire and the terminals will
cause measurement error.
Note:
- Linear voltage signal with its range below 500mV can be inputted from terminals 19+ and 18-.
- 0～5V, 1～5V or 0～10V signal can be inputted from terminals 17+ and 18-.
- 4～20mA current signal can be converted to voltage signal with an 250 ohm external resistor and then
inputted from terminals 17+ and 18-.
- If I4 module is installed in MIO slot, current signal can also be inputted from terminals 14+ and 15-, and
2-wire transmitter can be inputted from terminals 16+ and 14-.
