NX-ODx Digital Output Units Omron NX-ODx Digital Output Units are useful for general purpose as well as high-speed synchronous control. The high-speed I/O refreshing is possible by connecting NX-ODx output units to the NX-series EtherCAT coupler. The refreshing output can be synchronized with the control cycle of the controller. The output units provide 300ns (maximum) ON/OFF response time to enable high-speed and high-precision control. The NX-ODx units operate at a temperature range of 0ºC to 55ºC. The NX-ODx lineup includes 2-point, 4-point, 8-point, 16-point, and 32-point types with 3-wire, 2-wire, and 1-wire connection methods. Other features include a screwless detachable terminal block for easy maintenance and up to 16 digital output.
