CJ1W-DRM21 DeviceNet Master Unit

Smallest in the Industry! A DeviceNet Unit for the CJ Series that Boasts Industry-leading Performance and Functions

• Allows control of up to 32,000 points (2,000 words) per master, and ensures a high degree of simultaneity between data.

• Can be used as both a master and a slave at the same time.

• Equipped with settings and monitor functions aimed at improving both design and startup efficiency. Achieve maximum performance by using in combination with a Configurator.

• Files of master and slave settings can be uploaded and downloaded using memory cards, allowing effective debugging and easier setup.
