MELSEC iQ-R Series

Digital I/O modules are the senses of the automation system and provide an interface of various processes to the controller. Devices such as switches, indicator lamps, and sensors can be easily connected to the control system. The MELSEC iQ-R Series I/O modules have enhanced functions compared with the existing Series, one module can support various applications, reducing implementation and maintenance costs.
Modules can be selected according to requirements such as ease of wiring, number of points and characteristics of devices to be connected.
