Val Function
1 Analogue output (1)
2 Input 1 – custom 10V / 20mA
3 Input 1 - custom 60mV
4 Custom PT100 / J PT100
5 Custom PTC
6 Custom NTC
7 Input 2 - custom TA (2)
(1) The analog output in 20mA is calibrated with accuracy higher than 0.2 % f.s.; calibrate when
converting to 10V output.
(2) In the absence of calibration, accuracy is higher than 1% f.s.; calibrate only if higher
accuracy is required.
