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:
