HF read-write module with IO-Link

HF read-write module with IO-Link

Powerful HF-RWMs with IO-Link make system integration easy

HF RWMs with IO-Link extend the Contrinex system in the direction of Industry 4.0. They can be operated either as IO-Link devices or in standard I/O mode (SIO) with conditional binary outputs. In SIO mode the conditional output switch enables either tag detection or data block comparison.

These extremely flexible plug-and-play RWMs have been specifically designed for easy, cost-effective integration into existing control systems. All HF RWMs are fully compatible with ISO/IEC 15693.
