Product Description
Chenzhu CZ2077 Isolated Temperature Transmitter
The Chenzhu CZ2077 is a high-performance isolated temperature transmitter designed for industrial applications. It accurately converts signals from Resistance Temperature Detectors (RTDs) such as Pt100, Cu50, and Cu100 into a standard 4-20mA DC current loop signal. This device features input/output isolation, which protects control systems from ground loops and transient voltage spikes. With support for both 2-wire and 3-wire RTD connections and a user-configurable measurement range, the CZ2077 offers excellent flexibility and reliability for temperature monitoring and process control systems.
