Industrial Digital I/O

High-voltage industrial digital signals, also called binary signals, are control signals that range in magnitude from 0 to 48V with 24V being a typical high-level signal. This type of signal is used to communicate on/off status between remote devices and control equipment in relatively noisy industrial environments.

Maxim's industrial digital I/O products are used in industrial control equipment to receive and transmit these signals. These products primarily perform voltage level translation while providing circuit protection. Many of these circuits also perform serialization to allow economical operation through digital signal isolators that provide isolation protection to the control equipment.

Digital Input Level Translators/Serializers

These products provide the interface between high-voltage binary signals and industrial control equipment. Circuit functionality includes: voltage level translation, circuit protection, and optionally, serialization.

Digital Output Drivers

These products provide high-speed switching of high-voltage binary output signals for use in industrial control applications. These drivers feature very low on-resistance to reduce power usage and increase channel density.

Output Drivers for Binary Sensors

These output drivers are designed for industrial sensors that have binary outputs.  These devices accept 24V_DC power from the control device and provide lower voltage output (+5 or +3.3V) to power the sensor electronics.  They also feature a protected and configurable output drive architecture and configurable output logic.
