ET7S21 Dual Channel Input Loop Powered Isolator

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