The T700-0001 is a loop-powered isolator. Accepting a current input (typically 4-20mA), the TransPak T700 takes its power source voltage and the output current loop drive (500W, 10V compliance Max.) from the input current loop. The 1-20mA output current follows the input current signal. Span adjustment is provided to adjust for load variations. There are two (+) output terminals. Terminal #3 is for load less than 100W (e.g. current meter inputs) and terminal #4 for loads greater than 100W.

The T700 is designed for installation in industrial field environments. Circuitry is enclosed in the TransPaks rugged, die cast aluminum housing which is sealed for protection against corrosion, moisture dust and electrical noise such as radio frequency interference (RFI) and electromagnetic (EMI) interference. Top-mounted barrier terminals strip connections are provided. Optional mounting solutions and enclosures are provided.
