4-20 mA LOOP ANALYSER IT 52.51

Description

4-20 mA 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. operating on 4-20 mA DC input/output.

IT52.51 with its built-in power source and LCD display has four modes of operation, viz. 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. In these two modes, "QUICK CHECK" switch provides instant 4 mA & 20 mA output; for rapid check of zero & span end points. "QUICK CHECK" switch also has an intermediate Dial position; selection of this position allows precise intermediate settings between 4-19.99 mA on 10 turn potentiometer operated by a separate knob. 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 need of external power supply.

• FEATURES

• Tests/ calibrates instruments operating on 4-20 mA DC signal
• Multifunction capability: Sources 4-20 mA; Reads 0-20 mA; Simulates 2-wireTransmitter and powers 2 Wire Transmitter and measures its mA output in the range 4-20 mA
• High accuracy : 0.1% FSD - Bench top accuracy in a Tool Box Calibrator
• Instant check of 4 mA & 20 mA end points; and also fast check of any intermediate point in both Source & 2-wire Transmitter simulate mode
• Circuit design ensures stability of set current regardless of changes in voltage and load
• Large clear 3½ digit LCD, 0.5" high
• Portable, rugged and dry cell powered - Ideal for use in field & control room

 APPLICATIONS

• Used for rapid checking & simulation of 2 wire transmitters and checking Indicators, Controllers, Recorders, Current alarms, Data Loggers, Final control elements & computers etc.
