NX-series Digital Output Units NX-OD/OC CSM_NX-OD_OC_DS_E_7_1 A Wide Range of Digital Output Units from General Purpose use to High-Speed Synchronous Control * Transistor and relay 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. * Synchronous Units update their output status 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) ON/OFF response time of the high-speed model is 300 ns max, which enables high-speed, high-precision control. The screwless terminal block is detachable for easy commissioning and maintenance. Screwless clamp terminal block and Connector types (Units with MIL/Fujitsu Connectors) are significantly reduces wiring work. Up to 16 digital outputs in a space-saving 12 mm width. (Connector Types 30 mm width) The lineup includies 2-point, 4-point, 8-point, 16-point, and 32-point types with 3-wire, 2-wire and 1-wire connection methods. With output refreshing with specified time stamp, the Output Unit refreshes outputs at the time specified by the program. This enables highprecision output control independent of the control cycle of the Controller. * Connection to the CJ-series is possible by connecting with the EtherNet/IPTM Coupler.
