The KL5121 Bus Terminal can be used to implement a linear path control. The terminal reads an incremental signal, which can be supplied by an incremental encoder or a pulse generator, and switches the outputs when the counter reaches a previously defined state. The counter states can be transmitted to the terminal by the higher-level automation device in the form of a table. The position is acquired with the aid of the latch input, which is activated/deactivated by the gate input. Up to four 24 V outputs can be switched. The LEDs indicate the states of the signals at the various inputs and outputs.
