TE Connectivity’s (TE) Crompton Instruments Paladin Advantage, 254-TXX is a programmable transducer which provides measurement, isolation and conversion of all main electrical parameters into an industry standard DC output signal. The 254-TXX can be used in single and three-phase balanced or unbalanced three or four-wire electrical systems. 

The 254-TXX has an accuracy of CL0.2 and includes RS485 Modbus RTU communications protocol and pulse/alarm output as standard. The 254-TXX is an accurate device for the conversion of all main electrical parameters into 2 or 4 fully isolated Voltage or mA outputs. 

Designed, developed and manufactured in the UK, with an integrated microprocessor for exceptional handling of distorted waveforms. The 254TXX is ideal for low, medium and high voltage applications and provides a high protection against continuous and short circuit protection as well as galvanically isolated inputs and outputs 

- True rms measurement 

- User programmable configuration 

- Linear or Dual Slope Outputs 

- User friendly programming interface
