ACT20X Ex isolator/ amplifier
2
Page 2 ACT20X (Ex isolators family) Overview - Connects to process equipment in Class/Div, or Zone 0 - Zone 2 areas - ACT20X is not a zener barrier – it is an isolating amplifier - ACT20X is mounted in a safe area – or Zone 2, or Class 1 Div 2 area (always in a protective enclosure or panel) - Digital or analog types total 16 models - Signals are either from, or going to, the hazardous area. - PC configuration via CBX200 interface & WI-Manager software
