The digital input terminal KL1501 is an up/down counter and transports the counter value electrically isolated to the higher-level automation device. When used as a single-channel up/down counter (32 bits), the pulse is set via the clock input; the counting direction is specified via the U/D input. Furthermore, the input can also be used as a gate input for triggering the counter. In 2-counter mode, two separate counters (Clock and Clock1 inputs), parameterizable as up or down counters, are available with 16 bits each. Both outputs are switched according to the counter state, so that they can be used as fast control signals for field devices. The signal state of the inputs and outputs is indicated by light emitting diodes.

 

Special features:

  • suitable for fast counting tasks with counting frequencies up to 100 kHz
  • an up counter and a down counter, or
  • two separate up or down counters
