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.
