HART transparent repeater

HART transparent repeater

The ACT20X-HAI-SAO/2HAI-2SAO HART-protocol transparent current-supply isolators are capable of transmitting 4...20 mA signals from Ex zone 0 into the safe zone.
External sensors can be supplied with power through the device.


Integrated alarm contacts issue an alert in the event of a malfunction; this makes troubleshooting easier and increases system availability.


The rail mounted current-supply isolators are optionally available in one- or two-channel versions.
With 11 mm width per channel, the devices need little space in the electrical cabinet.
