[NEW: Compatible with global standards]


June 2023: UL Certification Added

[Max. connection units: 18]
Can be used in combination with the required units.Power supply units can be added according to the power supply requirements of sensors connected to remote I/O.

● Count units as connection units: Digital I/O, analog I/O, IO-Link master
● Do not count units as connection units: Power supply units, end units
● Device unit input/output points: 512byte (4096 points) * Total input/output value.

[Waterproof remote I/O IP65/67]
M12 connector and M8 connector are adopted.Since the control panel is not required, control panel cost can be reduced.

[IO-Link master]
8 ports per unit. Since only the IO-Link master can be expanded, up to 136 IO-Link components can be connected to one device unit.

The IO-Link master can occupy up to 64 bytes (512 points)/unit. Data size per port can be adjusted according to the data size of IO-Link components.

[Easy-to-use design]
I/O status is displayed with 3-color LEDs
Green: Normal
Red: Error (disconnection, communication error, etc.)
Orange: Information (exceeding the set value, etc.)

[Device unit setting tool]
Software (RTXTools) for setting and monitoring the device unit, IO-Link master and each unit is available free of charge from the CKD website.
