ASCO introduces the first discrete output device (class A), the new Profibus PA operator. The Profibus PA operator conforms to the PA profile V3.0 (discrete output) and can be mounted to many 2-way, 3-way and 4-way low power pilot valves. Some of the key benefits of this device are the diagnostics and manual override. Its diagnostics include cycle time, travel time, self-calibration, open and short circuit detection, manufacturer information, tag and serial numbers. The unit is approved to FM, CSA, ATEX, CE and Profibus conformance.
