TxIsoLoop-2

Description

The TxIsoLoop-2 provides signal protection by electrically isolating the input signal from the output.

The TxIsoLoop-2 helps simplify your application and avoid undesirable ground loops by providing single and dual loop galvanic isolation.

The 0/4-20mA input is measured and an identical isolated signal is reproduced at the output. Power is drawn from the 0(4)-20mA input loop, thus no auxiliaty power or an external power supply is needed. The TxIsoloop-2 also features two 4-20mA outputs.

Re-Ranging

If you require any other range we can reprogramme this for a £5 fee (select option above) - or alternatively you may wish to invest in the TxConfig Kit, which will allow you to totally configure and re-configure the instrument yourself.
