Atex, IECEx, FM, NEPSI, TIIS, GOST. Speed monitoring. Professional series of galvanically isolated speed monitors for detecting exceedances and undershootings of ranges, as well as windows and thresholds. This series is suitable for various environments and equipped with a variety of approvals, allowing the signal conditioning devices of the IM series to be installed in a wide range of applications. Features of the IM series speed monitoring: Operating range 0.06–600,000 minutes, storage of up to 8,000 measurement values via ring buffer, supports parameter configuration via PC (FDT/DTM), switches on the front panel or HART connection, complete galvanic isolation, Ex pulse output, LCD display, transistor output can also be used as a pulse divider to increase utilization depth, LED indication of error and operating status, supports a shutdown delay to prevent shutdowns due to frequency jumps.
