Controlling cranes and drilling derricks often involves the use of a joystick. Because these instruments are moved in various directions by the operating personnel, their motion is reflected in resistor changes. One resistor responds to forward and reverse motion while the other one changes with sideways motion. For this and other applications involving 0 V … 10 V voltage sources, Pepperl+Fuchs offers voltage inputs from our LB system remote I/O solution.
These voltage input modules have type of protection Ex i terminals and are suited for use in Zone 2, Class I/Div. 2 explosion-hazardous areas. As 1-channel versions, they are perfect for users who appreciate system granularity and easy commissioning. Galvanic isolation separates the inputs from bus and power. In addition, our voltage inputs are hot-swappable, which allows quick and easy module replacement without time-consuming system shutdowns.
