This document lists and describes all current Opto 22 SNAP PAC System part numbers, including PAC Project software, SNAP PAC controllers, and SNAP I/O modules of all kinds. SNAP PAC mounting racks and SNAP power supplies are also listed.
SNAP I/O analog input modules are part of Opto 22's SNAP PAC System. This document includes descriptions, specifications, and wiring and dimensional diagrams for the following analog input modules:
Antwerp-based AAQUA NV has specialized in engineering and constructing industrial wastewater treatment plants since 1999, with customers all over the world. Where possible, the company also adds value to customer waste, either by recycling wastewater to drinking water quality or by capturing the energy in the water to reduce fuel costs.
Initially AAQUA often worked with a subcontractor to automate treatment, but in 2005 they began offering automation themselves. To do so, the small company needed an automation system that was Ethernet based, flexible, reliable, offered remote access, and was easy to learn.
In this case study, read how they found that system and how they use it today.
This document is a statement of compliance with the EU Directive 2015/863/EU, Restriction of Hazardous Substances (RoHS 3). This document lists Opto 22 products that comply with the substance restrictions of the RoHS 3 directive.
This document lists all Opto 22 part numbers that have the Underwriters Laboratory (UL) approval.
This document is the Manufacturer's Declaration for the listed products as mentioned in the attachment - to which this confirmation refers - that they are in accordance with the mentioned European, international and/or national standards and regulations.
This overview describes the four integrated components of the SNAP PAC system: software, controllers, brains and I/O. This hardware and software system is designed for industrial control, remote monitoring and data acquisition.
