The C48CB is a three preset batch counter. The C48CB has a secondary counter that can be used for batch counting or to keep a total count. This secondary counter can be programmed to operate in one of eight operating modes. Outputs 1 and 2 are assigned to the primary process counter. Output 3 is assigned to the secondary Batch/Total counter or relay outputs. Units with solid-state outputs have a user input terminal available. The relay model has a relay output for 2 and 3 with output 1 as solid state only. The C48C Series uses four front panel push-buttons to program the operating modes, data values, and changing the viewed display. The series can be configured for one of two numeric data entry methods, digit entry or automatic scrolling. The C48C Series has programmable user inputs and a programmable front panel function key.
