Summary: | The interface master (5) and interface slave (1) are connected by lines (2,3) and interface conductor (4). The slave has interface IC (7) connected to the actuator (12) and sensor (13) through respective switches (8,9). A transformer (14) and capacitor (15) connected in series to the transformer primary, are provided between the IC and interface conductor, and IC for providing galvanic separation between the conductor, and actuator and sensor. LED (16) and diode (17) are shunted across the capacitor (15). Zener diodes (23-25) are connected between the galvanic separation transformer and the IC (7) to serve as protection wiring for the IC that is connected to the actuator and sensor through switches (8,9).
Beschrieben und zeichnerisch erläutert ist ein Aktuator-Sensor-Interface-Slave (1) mit zwei Anschlüssen (1, 2) zum Anschluß des Aktuator-Sensor-Interface-Slaves (1) an eine Aktuator-Sensor-Interface-Leitung (4), mit einem Aktuator-Sensor-Interface-IC (7), mit einer Ein-/Ausgangsschalung (8, 9) und mit mehreren Ausgängen (10) und mehreren Eingängen (11) zum Anschluß von Aktuatoren (12) und Sensoren (13). DOLLAR A Erfindungsgemäß ist zwischen den Anschlüssen (2, 3) und dem Aktuator-Sensor-Interface-IC (7) ein Transformator (14) zur galvanischen Trennung zwischen der Aktuator-Sensor-Interface-Leitung (4) und den Aktuatoren (12) und den Sensoren (13) vorgesehen. |
