NX-series Digital Mixed I/O Units NX-MD CSM_NX-MD_DS_E_2_2 Digital Mixed I/O Units for High speed Synchronous Control • DC Input/Transistor Output Units for the NX-series modular I/O system. • Connect to other NX-series I/O Units and EtherCAT Coupler units using the high-speed NX-bus. • One Unit enables synchronous Units to update the status of input devices to the controller and the output status of synchronous Units according to the controller's instructions every EtherCAT cycle. Features • High-speed I/O refreshing is possible by connecting with the NX-series EtherCAT Coupler. • Output refreshing can be synchronized with the control cycle of the Controller. (Synchronous refreshing) • Connector Types significantly reduces wiring work.
