8-port master brings fast standard I/Os and IO-Link together

Do you want to transmit standard signals as quickly as possible and use IO-Link at the same time? Then use one of our IO-Link masters, which we offer with 1, 2, 4, and 8 ports: When configured accordingly, they can transmit all standard signals up to 16 I/Os in just 1.27 ms – regardless of how many bytes of IO-Link data are transmitted in parallel. Every M12 socket has two signals that can be configured as two I/Os or one I/O and IO-Link communication.
