The EL1512 EtherCAT Terminal is an up/down counter. It transmits the counter state to the higher-level automation device in an electrically isolated manner. When it is used as a single-channel up/down counter (32 bit), the pulse is set via the clock input, while the count direction is set via the up/down input. The input can also be used as a gate input for triggering the counter. In two-counter mode, two separate counters (Clock and Clock1 inputs) are available, which can be parameterised as up or down counters. The signal state of the inputs is indicated by light emitting diodes. The EL1512 is particularly suitable for simple counting tasks, e.g. in connection with flow meters.
