Current loop isolation 4-20 mA version 1 or 2 channels

The TxIsoLoop is a galvanically isolated 3000 Vac DIN rail-mounted unit.

Signal isolators TxIsoLoop-1 (1 channel) and TxIsoLoop-2 (2 channels) provide signal protection by electrically isolating the 0 (4) -20 mA signals. They prevent measurement errors due to different voltage potentials or undesirable ground loops commonly encountered in instrument installations. The 0 (4) -20 mA input is measured and an identical isolated signal is reproduced at the output. Power is drawn from the input current loop, so no additional power supply is required for operation.
