Instruction Manual
• Compact bimodal to IO-Link device converter that connects discrete inputs and sends
the value to the IO-Link Master
• Enabled Delay Modes: ON/OFF Delay, ON/OFF One-shot, ON/OFF/Retriggerable One-
shot, ON/OFF Pulse-stretcher and Totalizer
• Measurement Metrics: Count, Events Per Minute (EPM), and Duration
• Discrete Mirroring: Discrete signals (In/Out) from all eight ports can be mirrored to any
of the eight ports, Discrete Out, or the host white wire output
• Outputs a discrete value as received from IO-Link Master Process Data Out
• Discrete input/output can be independently configured as NPN or PNP
• Rugged over-molded design meets IP65, IP67, and IP68
• Connects directly to a sensor or anywhere in-line for ease of use
• R95C IO-Link hubs are a quick, easy, and economical way to integrate non-IO-Link
devices into an IO-Link system

Overview
The R95C-8B21-KQ hub connects two discrete channels to each of the eight unique ports, providing access to monitoring and configuring those
ports with an IO-Link master. Host mirroring is available where a selected port input/output discrete signal can be routed to Pin 2 (male) on the PLC/
Host connection.
