ETM442 is programmable digital timer based on a microcontroller with a relay output and three inputs for start, reset and gate. Selecting the type of counting (up or down), 9 different time bases, output types sensor types (PNP or NPN), functional reset input and parameter access protection on 3 levels is made easy via the front panel keypad. The values are viewed on 2x4 digit display. With the memory function, timing condition in the event of a process or power failure and completes when normal production resumes or when power is restored.
