C48C
The C48C features a 7 segment, 2 line by 6 digit backlit LCD display. For the backlit versions, the main display line is red and shows the count value. When preset 3 or output 3 is viewed in the secondary display, the Batch/Total value is viewed in the main display. The smaller secondary display line is green and can be used to view the prescaler value, preset values, output time values or Batch/Total count values. The C48CB has a secondary counter that can be used for batch counting, or to keep a total count. This second counter can be programmed to operate in one of eight operating modes. Outputs 1 and 2 are assigned to the primary process counter (C1). Output 3 is assigned to the secondary Batch/Total counter (C2). The relay model has a relay output for Output 2 and Output 3 (Batch/Total). Output 1 is available only as solid-state. The unit has NPN current sinking, open-collector transistor outputs. All relay output boards are field replaceable. The C48C offers a choice of nine programmable counting modes for use in applications requiring bi-directional, anti-coincidence, and quadrature counting. The unit may be programmed to register counts on both edges of the input signal providing frequency doubling capability. DIP switches are used for input configuration set-up and to provide a Program Disable function. Four front panel push-buttons are used for programming the operating modes and data values, changing the viewed display, and performing user programmable functions, i.e. reset, etc. The C48C can be configured for one of two numeric data entry methods, digit entry or automatic scrolling. The digit entry method allows for the selection and incrementing of digits individually. The automatic scrolling method allows for the progressive change of one through all digit positions by pressing and holding the "up" or "down" button. The C48 Counter has programmable User Inputs and a programmable front panel function key. The user inputs can be configured as sinking (active low) or sourcing (active high) inputs via a single plug jumper. The Program Disable DIP switch, a user-programmable code value, an external user input (selected for Program Disable), and the Accessible value parameters can all be utilized to provide multi-level protection against unauthorized changes to data values and unit configuration. The unit is constructed of a lightweight, high impact plastic case with a textured front panel and a clear display window. The front panel meets NEMA 4X/IP65 specifications for indoor use, when properly installed. Multiple units can be stacked horizontally or vertically. Modern surface-mount technology, extensive testing, plus high immunity to noise interference makes the C48 Counters extremely reliable in industrial environments.
