Reliable Industrial Electronic Part ACT20X-2HTI-2SAO-S

The ACT20X-2HTI-2SAO-S is a 2-channel Ex signal isolating converter from Weidmüller. It transmits analog signals from RTD, thermocouple, and 0/4...20 mA sources from hazardous areas (up to Zone 0) to the safe area with 3-way galvanic isolation. The module supports SIL 2 functional safety per IEC 61508 and is configured via FDT/DTM software .
