ARD-A Series

The Remote I/O System for Industrial automation.

The ARD-A series analog remote I/O units provide input/output expansion and communication for various devices using DeviceNet protocols. The ARD-A series provides high measurement accuracy and excellent noise immunity using differential input method. Up to 63 units can be expanded per master unit and power and communication systems can be built easily using just the communication connection. Various user-friendly functions and simple mounting methods allow flexible application in diverse settings.
