I/O modules should be high density, easy to wire and configure, and reliable: Opto 22
Opto 22 says density, ease of wiring, reliability, and auto-recognition setup software are must-have I/O module features.
Opto 22 Snap Terminal Extenders
Opto 22's Snap Terminal Extenders are 6-ft long cables that provide neat, bundled connections from analog and digital I/O module terminals to custom breakout boards. Snap Terminal Extenders snap neatly into the top of Snap I/O modules and terminate with flying leads (pre-stripped and ready for wiring) at breakout boards that facilitate connection to field I/O. By providing snap-in, easy to trace wiring from the module to the device, Snap-TEX cables reduce wiring mistakes, eliminate incidences of loose connections at the top of the module, while also speeding and simplifying initial wiring and subsequent maintenance and replacement. www.opto22.com
I/O modules should provide greater density, be easy to wire and configure and deliver high reliability, explains Tom Edwards, senior technical advisor, Opto 22.
Edward says that those buying and specifying I/O modules should consider these topics carefully:
- Density : Ideally customers are looking for greater density to aid them in reducing the required panel space, as well as the per I/O point cost of their industrial automation and control applications.
- Ease of wiring : Wiring, installing, and assembling I/O systems is often expensive and time-consuming. Installers must be careful to avoid mixing terminations, particularly in cases where several hundred devices terminate in a single cabinet. Customers are grateful for any solution that helps them address these issues and reduce the time, expense, and complexity associated with wiring their I/O modules to field instrumentation and devices. Such a solution would include Opto 22's Snap TEX cables, six foot long, jacketed, pre-wired cables that provide neat, bundled connections from modules to field devices, terminal strips, and breakout boards. (See explanation, right.) By providing snap-in, easy-to-trace wiring from the module to the device, these cables reduce wiring mistakes, protect terminal connections from dust and jarring, and also speed and simplify both initial wiring and subsequent maintenance and replacement.
- Ease of module configuration : Customers are always pleased with any type of helping hand they can get in configuring their modules. Having auto-recognition and auto-configuration features in the software they're using can save tons of time and make the often tedious but always necessary first step of module configuration a lot easier.
- Reliability : It goes without saying that customers want durable, guaranteed for life I/O modules.
