Feature: 1. WORKING PRINCIPLE: AC current transmitter SZJ series can measure and isolate the AC current in the grid or circuit in real time, and transform into 4‑20mA DC output signal 2. WIDELY USED: The current transmitter can be connected with a variety of AD to form a variety of digital centralized acquisition system, or output to PLC and other components of automatic control system, or connect with the traditional analog, digital indicating instrument to display measurement values 3. SAFETY ISOLATION: AC current sensing switch has the characteristics of strong overload capability, high accuracy, high isolation, high security, low power consumption, strong interference resistant ability and so on 4. INSTALLATION MODE: AC current transmitter using guide rail installation or screw fixed, easy installation and use, widely used in the field of industrial automation 5. FAST AND ACCURATE: PLC control current sensing switch with input, output and power isolation, accuracy for 0.5%, response time
