Product Details:

ET7S21 / ET7S22 are Single / Dual channel Input Loop powered Isolators used for Electrical Isolation of 4–20mA signal, Electrical Isolation eliminates common mode voltages, prevents ground loops measurement errors and protects expensive systems from field faults.

The model is Input Loop powered by 4-20mA and does not need auxiliary supply, thus saves wiring cost and power dissipation.
High reliability of Loop powered Isolator ensures system uptime and low maintenance costs.

ET7S21 / ET7S22 is well suited for 4 wire transmitters and Aux. output signals from Automation Systems and Devices like AC drives, Analytical Instruments, PLC, etc.
