The Rockwell / Allen-Bradley 1771 Series Encoder / Counter Modules maintain a count, independent of the processor, of input pulses that typically originate from such devices as quadrature type encoders, high speed optical beam counters, and certain types of switches. The module is capable of making decisions based on the count total by comparing it to previously programmed values and activating either one or both of its outputs based on the results of the comparison. The module can also return the accumulated count to the processor for arithmetic computations or display.
The module also provides inputs for a marker signal from an encoder and a voltage level signal from a limit switch to allow for home positioning. In the count mode, the direction of the count can be changed either from the processor or, for speed critical application, at the module itself through an external switch. The maximum detectable input pulse frequency of the module is 50kHz.
