The new ProLine BC Counter is the perfect solution for multi-batch counting and tracking total pieces.  With the ability to add two inputs, you can do multiple batch counts and track total pieces.  Two standard outputs each have a N.O. and N.C. output to allow you to inhibit upstream/downstream devices or activate tower lamps, alarms, or provide an input to a host controller.  The outputs can be configured to latch on until reset or momentarily latch for a set time.  The BC Counter comes with one input sensor w/ 3m cable and one 3m 4-wire output cable (flying leads).  An additional sensor and/or I/O cable can be added optionally.
