Maximum common mode voltage respect to
GND When configured for DC source:
MAX +20Vdc
When configured for generic 0...10V:
MAX ±20Vdc
Bidirectional DC current measurement input
– JU - SHUNT
Input type Four differential analogue inputs for DC voltage
measurement, optimized for the connection towards
external shunt sensors.
Galvanically insulated.
Type of measurement True RMS measurements (TRMS)
Sampling frequency 10Khz
Input impedance > 28Kohm
Maximum DC voltages applicable Max ±200mVdc
Insulation voltage 350Vac
Surge immunity 1KV (class 2) trans
ient 1,2/50μs (EN61000-4-5)
Resolution 12 bits
Measurement accuracy <0,2% F.S. (excluding the error of the shunt)
The measurement accuracy of the DC current depends
on the accuracy class of the used shunt.
We suggest the use of shunts with accuracy class of 0,5
or better.
Bidirectional DC current measurement input DC
– JU - HALL
Input type Four differential analogue inputs for DC voltage
measurement, optimized for the connection towards
external HALL effect sensors.
The galvanic insulation is provided by the sensors.
No injection leakages.
Type of measurement True RMS measurements (TRMS)
Sampling frequency 10Khz
Maximum DC currents applicable Nominal range from 50 to 600A DC.
Insulation voltage 500Vac CAT.III
3KVdc on transient < 60s.
Resolution 12 bits
Measurement accuracy <1,5% F.S.
Analogue input PT100 - JP
Input type Analogue input for the measurement of the plant battery
temperature, through PT100.
The resistance is calculated by measuring the differential
voltage on the sensor, injecting a constant current.
PT100 sensors with two or three wires can be used.
Not insulated.
Temperature measurement range From -70°C to +650°C
Resistance measurement range From 20 Ohm to 330 Ohm (broken wire warning over 333
Ohm).
Sampling time <300ms
Injected current 0,6mA nominal
Resolution 12 bits
