2、 Core functions
Signal isolation and conversion
Receive the ± V, ± mA, and ± mV signals generated by the equipment, convert them into the signals required by the customer (such as 0-5V, 4-20mA, etc.), and isolate and transmit them to the PLC/DCS/display instrument in the control room.
By using electromagnetic isolation technology, the power supply, input, output, and distribution are isolated from each other to suppress signal interference and solve the problem of «ground» potential difference.
High precision and high reliability
Transmission accuracy: 0.1%, linearity: 0.1%, low-temperature drift: 0.0035% F.S./℃.
Industrial grade temperature range: -25 ℃~+71 ℃, suitable for harsh industrial environments.
Multi scenario applicability
Supports various types such as passive series, active series, and gain adjustable amplifier modules to meet the installation requirements of different occasions.
Provide regular and intrinsic safety products to meet the safety requirements of explosion-proof areas.
Flexibility and Scalability
Supports multiple power inputs (24/15/12VDC) with power reverse protection function.
Seamless integration with ABB’s AC800M controller and S800 I/O system, supporting fiber optic expansion.
