The 720250 Voltage Module has a 10 MS/s sample rate, 12-bit resolution, 3 MHz bandwidth, 2 isolated channels, a maximum input voltage (DC+ACpeak) of 800 V*2, 200 V*3, DC accuracy of ±0.5%, and high noise immunity.
Applicable to DL350, DL850, DL950 and SL1000.
In a voltage sensor, there is normally a bridge circuit and voltage circuit breaker with a resistor for a sensing element and two resistors dividing the voltage.
