Omron, GX-[]D16[]8 / []D32[]8 Series

Digital I/O terminal with industry standard e-CON connectors.
A common terminal is provided for each connector. The I/O terminal and the sensors can be connected directly.
Input response time can be switched for high-speed processing.
Selectable node address setting methods: setting with rotary switch and with tool software. When setting the nodes with rotary switch, setting is easy and node identification becomes possible for maintenance.
