Sobre este producto
- ✅【Input power】The signal generator can be used for current analog 4-20mA output by manually adjusting the potentiometer to produce 4-20mA current output.
- ✅【Output Current】 The output current can be automatically constant at the set value according to the adjustment, also can be used as a constant current source, its maximum output current does not exceed 20mA.
- ✅【Recommended Current】The input power of the signal generator is DC3.3-30V, and the recommended power supply is 12-24VDC.
- ✅【Support equipment】The module power consumption current is less than 30mA, support general equipment.
- ✅【Applicable range】The general-purpose power supply of the module can be used for PLC, inverter, servo.
