KL1501 | Up/down counter 24 V DC, 100 kHz

The up/down counter counts binary pulses, and transmits the counter state, in an electrically isolated form, to the higher-order automation device. Using the up/down input, the (32 bit) counting direction of the KL1501 Bus Terminal can be changed. The gate connection can be used to control the triggering. Using the Clock1 input, it is possible to implement two (16 bit) counters. The Bus Terminal contains two inputs that indicate their signal state by means of light emitting diodes. Both outputs are switched conform to the counter state, so that they can be used as fast control signals for field devices.
