IsoPAQ-110R is a Transmitter Repeater for powering and isolation of a non-isolated 2-wire transmitter.
Thanks to the isolation, the 4-20 mA transmitter signal can be connected to a grounded input circuit of a control system without risk for measurement errors due to ground loops.
The Transmitter Repeater needs no power supply, which contributes to reduced installation costs. The high reliability ensures a safe system operation and low maintenance costs.

1) Average TC in specified operating temperature range
2) As far as relevant the standards and rules mentioned above are considered by development and production of our devices. In addition relevant assembly rules are to be considered by installation of our devices in other equipments. For applications with high working voltages, take measures to prevent accidental contact and make sure that there is sufficient distance or insulation between adjacent situated devices.
3) Minor deviations possible during interference
