KL1512 | 2-channel up/down counter, 24 V DC, 1 kHz, 16 bit

The up/down counter counts binary pulses, and transmits the counter state, in an electrically isolated form, to the higher-level automation device. Optionally the KL1512 Bus Terminal can be set up as an up or down counter (16 bit). The Bus Terminal contains two inputs that indicate their signal state by means of light emitting diodes. The KL1512 is particularly suitable for simple counting tasks, e.g. in connection with flow meters.
