B&R X20PS4951
Open circuit and short circuit detection Simple implementation of potentiometer inputs 4x supply In order to connect potentiometers, modules must first be supplied with the appropriate voltage. The potentiometer supply module can be used to supply four potentiometers with ±10 V. The data is evaluated using standard analog input modules.
