Description

Description

The OMDC-DM8000 is an economicalmicroprocessor-based digital tachometersystem capable of measuring shaft speedslower than 1 RPM. With an on-boardmicrocomputer coupled with sophisticatedinternal software and a quartz crystalcontrolled reference frequency, theOMDC-DM8000 is able to maintain accuracyof ±0.04%, even if the shaft is uneven. TheOMDC-DM8000 is field programmablethrough the easy-to-use frontpanel interfaceand can be configured to display any desiredunit of measure. Large 13 mm (½") 4-digitLED display numbers allow viewing underthe most adverse conditions.

The isolated 5 amp form C relay output canbe configured for many different alarmingconditions. Designed to use a variety ofinputs, including the hall-effect solid stateOMDC-PU-E Series pick-up, the systemdelivers trouble free operation at aneconomical cost. The OMDC-DM8000 offersthe same enhanced display options andcapabilities featured in our other digitalcontrol products, as well as the universalpower supply and rugged european-styleterminal strip.

The OMDC-DM8000 can be used in processapplications for monitoring speeds andrates, or counting discrete input signals.Process applications using counting may bebatching, filling, mixing, punching, cutting,drilling, diverting, or alarming. Whileprocess applications using speed or ratemonitoring may be conveyors, conveyorovens, material flow, rotational rpm,and testing.
