Remarks:
1. All dimensions are in mm.
2. General tolerance ±1mm.
3. Elucidation: 1:+15V 2:-15V 3:V0UT 4:0V
1. When the current will be measured goes through a sensor, the voltage will be measured at the output end.(Note: The false wiring may result in the damage of the sensor)
2.Custom design in the different rated input current and the output voltage are available.
