Description

The ATHiso current loop isolator converts 4-20mA or 4-12-20mA to an isolated voltage or current loop output.   The ATHiso current loop isolator isolates its input from output eliminating ground loops, common mode voltage errors, signal noise and resultant accuracy errors.  Available ATHiso current loop isolator models cover signals used in process control like 4-20mA,  4-12-20mA and 0-10V where any combination can be input or output, operating with fast response capability.  The current loop isolator power input is designed to operate over a wide range associated with process control, telecomm and sub-station auxiliary dc supply systems.  Some typical applications are current monitoring in automotive, traction, energy metering, industrial control, ac/dc drives, process control, rail transportation and ac motor driven devices like pumps.  For all products, a USA NIST, UK UKAS traceable calibration certificate and certificate of conformance are available.
