Single Phase AC Current Off-limit Alarm Transducer,output switch value signal as Relay passive contact signal or Open collect signal..
This transducer is a single phase AC current off-limit alarm transducer. It adopts high-precision isolation components to isolate the measured AC current signal and outputs switch value signal. The input signal is a single phase AC current signal and the output signal is a relay passive contact switch (or OC gate). When the AC current exceeds the set upper limit value or lower limit value, it will output the over limit alarm signal or under limit alarm signal, and the output signal is the relay contact signal. Within the input range, the action limit value of AC current can be set arbitrarily.
The input and output of this transducer are completely isolated; With the characteristics of high precision, high isolation and low thermal drift,this transducer is mainly used for the safety protection of various electrical control systems and other necessary protection devices.
This product features:
1. The input port and power port can withstand the surge impact of 4KV; It has the features of strong anti-jamming ability, safety and reliability.
2. It has relay passive contacts, OC gates and other output modes, making the product more widely used in a variety of security protection systems.
3. There are two types of installation, Standard 35mm DIN Rail and screw, which makes the installation simple and reliable.
