IO-Link® is a 3-wire industrial communications standard designed for linking sensors and actuators into control networks. In IO-Link applications, the transceiver acts as the physical layer interface to a microcontroller running the data-link layer protocol while supporting up to 24V digital inputs and outputs. Maxim transceivers support all IO-Link specifications.

Binary drivers use a standard 24V, 3-wire industrial interface. These drivers typically support high-side (pnp), low-side (npn), or push-pull configurations along with normally open (NO) or normally closed (NC) logic. Maxim’s binary drivers integrate transient protection that meets IEC 60255-5 surges up to ±1.3kV as well as OTP programming options to set 3.3V or 5V outputs, the timing of the power-on reset (POR) delay.
