1. Reliable work: Using shielded and twisted pair cables for better anti-interference ability, so that transmission and communication are more stable with long distances and multiple devices. 2. High precision: The adjustable output current signal range is 0mA to 22mA, while the digital display ensures high operating precision. 3. Better Safety: Comes with short circuit protection and reverse protection, the current signal generator is very safe. 4. Wider utility: can be applied to PLC panel debugging, equipment testing, frequency converter, servo motor speed regulation, etc. 5. Easy to install: Light weight combined with compact size makes it easy to install the rail, which can be completed in a few minutes. Specification: Item Type: Current Signal Generator.
