Factories are expanding to enable Industry 4.0, buildings are getting smarter, and robotics are continually evolving. Such widespread innovation drives designers in various industries to optimise and enhance their products. Maxim's industrial digital and analog I/O IC portfolio provides the highest levels of robustness in the market with the highest integration and software configurability for a more flexible solution.

High-voltage industrial digital input (DI) and digital output (DO) signals (also called binary signals), typically range in magnitude from 0 to 24V. Digital I/O signals are used in industrial automation and control equipment, operating in harsh and noisy environments to communicate on/off status between remote devices and controllers. Maxim's industrial digital I/O ICs perform voltage level translation while providing circuit protection. Many also perform data serialization to allow economical operation through digital signal isolators.
Analog I/O signals are used in both factory and build automation to enable smarter sensing and push intelligence at the edge. Maxim's best-in-class analog input (AI), analog output (AO) and configurable analog input/output (CIO) ICs provide the highest levels of system accuracy in the market with per channel software configurability. Factory calibration and robust integrated protection reduce overall system cost and size. Innovative designs decrease power consumption allowing operation of more channels without derating for ambient temperature.

Key benefits

  • Most robust solutions in the market with the highest integration.
  • Fast time to market with the best support in the industry.

Products

Digital input ICs

Industrial digital input (DI) ICs interface between high-voltage signals from sensors on the factory floor to the lower voltages found in automation and control equipment such as industrial controllers. Maxim's IEC61131-2-compliant digital input interface devices offer the smallest solution size, lowest power dissipation, and most robust operation with 1kV of surge protection and integrated diagnostics. Maxim's parasitically powered digital input IC reduces power dissipation by up to 60 percent and does not require a discrete isolated power supply.

Digital output ICs

Industrial digital output (DO) ICs are used for high-speed switching of high-voltage output signals in industrial automation and control applications. Maxim's digital output drivers have very low on-resistance (reducing power dissipation and allowing increased channel density), integrated surge protection, diagnostics, and allow safe demagnetization of inductive loads.

Configurable digital input/output ICs

Digital I/O devices allow a controller to configure a channel electronically as either a digital input or digital output, without the need to change hardware, thereby removing the limitation on the available card types. This provides greater design flexibility and reduces the costs associated with changes that may be required during project commissioning. Maxim's DIO products are fully IEC compliant, software-configurable and include the patented SafeDemag™ technology, which allows for quick and safe demagnetization of any size inductive load.

Configurable analog input, output & input/output ICs

Analog I/O devices enable communication over long distances for sensors on the factory floor or in building automation with control equipment. Software configurable analog I/O allows a controller to configure a channel electronically either as an analog input or analog output in either current or voltage mode without the need to change hardware. This provides greater design flexibility and reduces the costs associated with changes that may be required during project commissioning. Maxim's AIO products are fully IEC compliant, software-configurable and provide some of the smallest integrated solutions on the market.
