The Endress+Hauser reliable output amplifier with 1 or 2 channels, designed to ensure safe and precise control of active components such as control valves, actuators, I/P converters, or indicators. This intrinsically safe device separates and transmits analog 0/4 to 20 mA signals and offers bidirectional HART transparency for digital communication with smart actuators. With its compact design and galvanically isolated channels, this interface device provides open- and short-circuit monitoring for the reliable operation of critical equipment.
