CROMPTON INSTRUMENTS 254-TXX PALADIN ADVANTAGE UNIVERSAL PROGRAMMABLE TRANSDUCER
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 254-TXX 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.
