Pulse isolator, relay

Pulse isolator, relay

The ACT20X-HDI-SDO/ 2HDI-2SNO RNO/RNC isolating switch amplifiers are specially designed for recording NAMUR sensor signals and digital switching signals which originate from Ex zone 0.



Switching relays, optionally available with NO or NC contacts, transfer output signals to the safe zone.
Integrated alarm contacts issue an alert in the event of a malfunction; this makes troubleshooting easier and increases system availability.

The rail mounted disconnect-switch amplifiers are optionally available in one- or two-channel versions.


With 11 mm width per channel, the devices need little space in the electrical cabinet.
