Note: all the relays must have the common terminals (C1/2, C3/4, C6/7, C8/9) connected together.
Functional characteristics
Resolution of the analogue inputs Temperature probes: range -40T80 °C, 0.1 °C
Temperature measurement error Range -20T20 °C, ±0.5 °C (excluding probe)
Range -40T80 °C, ±1.5 °C (excluding probe)
Pressure measurement error The % error with a voltage reading with a range of input from 0.5 to 4.5
is ± 2% (excluding probe).
The error in the converted value may vary according to the settings of
parameters /9, /10, /11, /12
