Sensor Contact: +
• When current sensor status is o (open), leakage
<30 uA @ 30Vac/dc
• When current sensor status is on (closed), voltage drop
< .3 Vac/dc @ .1 Amp
< 1.6 Vac/dc @ .4 Amp
Sensor Feedback Output: ^
• Voltage output is proportional to current sensor range.
• Min. Input Impedance = 30K ohms
• Accuracy +/– 1% full scale
• Vripple < 10m Vac
