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.
Opto 22 SNAP digital output modules are designed to mount on SNAP PAC racks and be used with SNAP PAC brains and R-series controllers, both standard wired and Wired+Wireless models. You can choose from AC or DC output modules.
These modules are also compatible with SNAP D-series and legacy M-series and B-series racks, and they can be used with legacy Ethernet-based brains as well as other SNAP brains, such as the serial B3000 or the B3000-HA.
This data sheet covers the following part numbers:
Now you can safely and reliably sense and switch industrial-level electrical loads with your Raspberry Pi® and Opto 22 industrially hardened digital I/O.
This Selection Guide describes compatible I/O racks and modules, power supplies, and accessories that work with the Raspberry Pi and the Digital I/O Carrier Board for the Pi (OPTO-P1-40P). Specifications, dimensional drawings, and wiring diagrams for racks and I/O modules are included.
