Product Overview
Banner R90C-4B21-KQ is a compact 4-port discrete IO-Link hub designed for on-machine mounting in industrial environments. It consolidates multiple field signals into a single IO-Link connection back to an IO-Link master, reducing home-run wiring and simplifying panel layouts. Each M12 port supports configurable discrete input or output operation, allowing integration of sensors, limit switches, and actuators through one ruggedized device.
Built for harsh factory floors, the R90C series is engineered for IP67/IP68-rated installations when used with properly sealed M12 connectors. Operating from a 12V to 30V DC supply, it is suited for standard 24V industrial control systems common in automation, packaging, and material handling lines.

- Integrating limit switches and pushbuttons into IO-Link networks
Frequently Asked Questions
Does this unit function as an IO-Link master?
No. The R90C-4B21-KQ is an IO-Link hub and requires an upstream IO-Link master for communication to a PLC or controller.
What voltage does it require?
It operates on a 12V to 30V DC supply, commonly powered from a regulated 24V industrial rail.
Is it suitable for wash-down environments?
When properly installed with sealed M12 connectors, the housing is rated for IP67/IP68 conditions. Cable and connector integrity are critical for maintaining that rating.
Can each port be configured differently?
Yes. Each port can typically be configured as a discrete input or output depending on system setup and IO-Link master configuration.
Has this unit been tested?
This unit has been visually inspected and is in clean condition. It has not been functionally tested.
Four field signals, one clean IO-Link path back to the panel. If you are tightening up wiring on a machine or extending an IO-Link network without adding more conduit, this R90C hub is built for that job.
