4-20 mA Loop Analyzer (IT52.51)

4-20mA Loop Analyser, IT52.51 is a versatile portable instrument for rapid checking & simulation of 2 wire transmitters and checking Indicators, Controllers, Recorders, Current alarms, Data Loggers, Final control elements & computers etc.
IT52.51 with its built-in power source and LCD display has four modes of operation - Normal Source, 2-wire Transmitter Simulation, Normal Read and 2-wire Transmitter Read. Normal Source mode provides 4-20 mA DC output, 2-wire Transmitter Simulation mode modulates external power to pass 4-20 mA in the external loop. Normal Read mode measures input currents fed to the Analyser. 2-wire Transmitter Read mode supplies 27 Volts in series with the internal measuring circuit at the output terminals and measures 2-wire transmitter output, thus eliminating the need of external power supply.
