Product selling points and characteristics: 1. Reliable operation: shielded twisted pair cable is adopted, which has stronger anti-interference ability 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 very 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, compact size, easy to install guide rail, can be completed in a few minutes.
