2 Ch Digital Input

This Up/down counter 24 VDC, 100 kHz, 32 bit counter depth counts binary pulses, and transmits the counter state, in an electrically isolated form, to the higher-level automation device.

The AKT2G-DN-002 EtherCAT Terminal can alternatively be operated as:

• a single-channel counter (32 bit) that can be toggled between counting up and down via the U/D input (delivery state)
• a single-channel counter (32 bit) that is controlled via the gate connection
• two separate logic counters (32 bit) that can count in one direction only with the Clock 1 and Clock 2 inputs

The signal state of the inputs and outputs is indicated by light emitting diodes. The two outputs (Output 1 and Output 2) are switched in relation to the counter value and can thus be used as fast control signals for field devices. The AKT2G-DN-002 supports distributed clocks, i.e. the input data can be monitored synchronously with other data that are also linked to distributed clock terminals. The accuracy across the system is < 100 ns.
