Our ADM239-AA is a Din Rail Mounted Two Input Auto Averager Unit which is suitable for providing the average of two flow, temperature, pressure or other process input signals in SIL 1, SIL 2 and SIL 3 rated (EN 61508-2) safety instrumented system (SIS) loop applications. If either of the input process signals is lost, shut off or goes open circuit, the unit will automatically switch to a straight repeater of the remaining active input signal.
Guaranteed by the Amelec standard 10-year warranty.
