Overview of TH series signal isolators

TH series signal isolators (one in and one out, one in and two out) are electrical equipment connected between industrial field instruments and the control room. It effectively solves the field interference problem of industrial automation control system through the reliable isolation between power supply, input and output, and ensures the stable and reliable operation of the system. It is a general-purpose product that basically covers various signal isolation, conversion, distribution and other functional requirements of the automatic control system.

Features of TH series signal isolator

Measurement: DC voltage, DC current, etc.

Accuracy: ≤±0.1%RO

Isolation: Input, output, and power supply are completely isolated, with strong anti-interference ability

Output: 4~20mA, 0~20mA, 0~10V, 1~5V, 2~10V, etc.

Power supply: DC24V or AC220V

TH series of signal isolators support the base plug -in, easy assembly and disassembly, high precision, high linearity, strong anti-interference, long-term stability
