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/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-/two-channel versions. With 11 mm W per channel, the devices need little space in the electrical cabinet.
