1 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

3 Page 3 Digital types Product Definition Example description… ACT20X - 2HDI – 2SDO - S PS Digital input 1 from hazardous area Digital input 2 from hazardous area Digital output 1 to safe area - 2HDI -- 2SDO - Aux power input (19,2 – 31,2 Vdc) Screw terminals

4 Page 4 Housing Features 22,5mm wide format 1 or 2 channel variants for higher density Blue covers identify hazardous connections Function LEDs show operaring status Terminal numbers visible on front Terminal coding prevents mis-wiring Power cross - connections via the mounting rail (option coming)

5 Page 5 9 x Digital types ACT20X range PS Pulse Isolator Solenoid/Alarm Driver

6 Page 6 7 x Analog types ACT20X range PS HART input isolator IIII HART output isolator

7 Page 7 Customers Target customers:  Oil refineries – operators of hazardous processes  Oil & Gas Industry OEMs – or systems integrators supplying controls and drives  Waste Water systems integrators – sludge handling plant  Fuel handling OEMs – for power plant  Metering / gas distribution companies
