Product selling points and characteristics: 1. operation: shielded pair cable is adopted, which has stronger anti-interference and more stable long-distance multi equipment transmission and communication.2. High precision: the adjustable output current signal range is 0mA 22mA, and the digital display ensures the high precision of operation.3. Better safety: equipped with short circuit protection and reverse protection, the current signal generator is safe.4. Wide application: it can be used for PLC panel debugging, equipment testing, frequency converter, servo motor speed regulation, etc.5. Easy to install: light weight, size, easy to install guide rail, can be completed in a few minutes.Product parameters:DC 24VPower supply voltage range: DC15V -- DC28VAC AC220V (optional) power supply range: AC85-264V or DC110-370VPower consumption Less than 2wOutput current range: OmA -- 22mA (settable, factory setting 0-20/4-20mA)Output regulation accuracy 0.1mA, error Less than 0.05mA, load sampling resistance Less than 500 Working environment: 0-40 , relative humidity Less than 80%Color: As ShownMaterial: plasticVoltage: D-(0-20mA AC220V)Package Contents:1 x Current Signal GeneratorOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
