Guide to Digital IO
The digital IO, or digital input-output module, assists with industrial automation processes and controlsMany applications use digital I/O devices for analyzing, controlling and monitoring purposes. For example, USB digital I/O devices only require one connector for computer controls. Other digital IO devices monitor alarms, control timers, industrial processes, test production equipment or are used to examine laboratory materials. Digital I/O boards also apply to automated machines, lamps, digital sensors, remote transducers and motors. Digital I/O cards monitor security systems, field sensors, energy management systems and factory automation. Here are some factors to consider before buying digital I/O systems for your business:
1. Ensure that digital I/O devices meet industry standards.
2. Determine the need for digital I/O devices with one or more connections, inputs and outputs.
3. Find digital IO modules that are cost-effective.
Action Steps
The best contacts and resources to help you get it done
Find digital I/O modules that pass industry standards
When buying digital I/O modules and other devices, be sure that they are certified to operate in business or factory conditions.
I recommend:
National Instruments produces digital I/O solutions that are suitable for design, test and control applications. Jameco Electronics manufactures digital I/O devices and other components that exceed industry standards.
Choose digital I/O devices based on need, number of connections and other features
Most digital I/O devices or modules feature short circuit protection, LED displays for effective monitoring of different processes and multiple connections that allow for different capabilities.
I recommend:
Advantech manufactures digital IO modules with built-in microprocessors, and digital IO cards with as many as 32 input and output channels. MKS Instruments features a product line of Ethernet-based digital I/O modules.
Look for cost-effective digital IO modules or devices
Shop for digital I/O devices from competing manufacturers to decide which items fit in with your budget.
I recommend:
ICP DAS USA distributes remote Ethernet, web-based Ethernet and other data acquisition digital IO modules. Free shipping is also available if ordering within the United States and the total reaches $200 or more. In addition to offering digital IO and other devices at competitive prices, AutomationDirect offers free shipping if order totals are $300 or more. Same-day shipping is also available for most of their products.
Tips & Tactics
Helpful advice for making the most of this Guide- Power requirements, user connections, circuit voltage, operating temperature range and relative humidity range should be some of the top specifications to watch for when picking digital IO devices.
- Most digital I/O devices are certified by Underwriters Laboratories, the Consumer Electronics Association and the Canadian Standards Association.
