Factories are expanding to enable Industry 4.0, buildings are getting smarter, and robotics are continually evolving. Such wide spread innovation drives designers in various industries to optimize and enhance their products. Our industrial digital and analog I/O IC portfolio provide the highest levels of robustness on 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 by industrial automation and control equipment, operating in harsh and noisy environments, to communicate on/off status between remote devices and controllers. Our 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. Our 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 on the market with the highest integration.
- Software configurability provides flexibility and reduces end product SKUs.
- Fast time-to-market with the best support in the industry.
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 as either 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. Our AIO products are fully IEC compliant, software-configurable and provide some of the smallest integrated solutions on the market.
Industrial Digital IO Evaluation Boards and Peripheral Modules
Peripheral module boards (PMBs) provide an easy way to evaluate our digital IO devices.
PMB Key Features
- Powered from a Single 3.0V to 5.5V Logic Supply, Without the Need for a 24V Field Supply
- Configured for IEC 61131-2 Type 1 and Type 3 Sensor Inputs
- Proven PCB Layout
- Works with USB2PMB2# or USB2GPIO# Adapter and Munich GUI Software
