The expansion module JXM-IO-E34 is the universal decentralized component for mobile machinery. With its balanced I/O configuration, it can handle almost all decentralized tasks and significantly reduce wiring effort. The module is particularly characterized by its 12 current-controlled outputs, enabling precise control of hydraulic valves. The reference output allows the use of standard sensors and supports pre-processing applications. Communication with the JXM-IO-E34 takes place via CANopen, making it easy to integrate the module into standard CAN networks of mobile machines. Thanks to its robust, encapsulated housing, the expansion module can be used flexibly under harsh environmental conditions.
