Production Specification

The SNAP-ODC-32-SNK digital output module (load sinking) provides 32 digital output channels in one compact SNAP module. This module is ideal for OEMs and others with applications with high point counts, or for those requiring a large number of digital output channels on one SNAP I/O rack. The high-density configuration reduces per-point costs of digital I/O systems by providing up to eight times as many I/O channels in the same space.

If you're unsure whether you need a sinking or sourcing module, see the sinking/sourcing demo or watch the brief Sinking vs. Sourcing video.

Part of the SNAP PAC System, the module mounts on a SNAP PAC rack with a SNAP PAC brain or rack-mounted controller. Analog, digital, and serial I/O modules can all be on the same rack. Such an I/O unit is also well suited for PC-based control or for use as intelligent remote I/O for an Allen-Bradley Logix PLC system, such as ControlLogix, MicroLogix, or CompactLogix.

For easy field wiring, use the SNAP-ODC-HDB or compact SNAP-UDC-HDB breakout rack and the SNAP-HD-BF6 header cable. A wiring harness with flying leads (SNAP-HD-CBF6) is also available.

NOTE: If you need a Factory Mutual-approved version, see the SNAP-ODC-32-SNK-FM.

For switching signals with higher current, see the SNAP-UDC-HDB-G4 breakout board, which mounts G4 input modules that handle up to 3 amps per point (G4 modules are sold separately).

SNAP PAC System Product Guide

This document lists and describes all Opto 22 SNAP PAC System part numbers, including PAC Project software, SNAP PAC controllers, SNAP PAC brains, and SNAP I/O modules of all kinds. SNAP PAC mounting racks and SNAP power supplies are also listed.

SNAP High-Density Digital Modules Data Sheet

SNAP I/O high-density digital modules from Opto 22 provide 16 or 32 digital input or output points in one compact SNAP module. These modules are ideal for OEMs and others who have high point-count applications, or for anyone requiring more than 64 digital points on a single SNAP PAC rack. The high-density configuration reduces per-point costs of digital I/O systems by providing up to eight times as many I/O points in the same space.

SNAP high-density digital modules are part of the SNAP PAC System. They can also be used as part of intelligent remote I/O with an Allen-Bradley Logix PLC system.

HDD modules require a SNAP PAC R-series controller or a SNAP PAC brain for I/O processing. These modules work with standard wired controllers and brains and with Wired+Wireless models.

SNAP High-Density Digital Module User's Guide

This guide covers how to install and test SNAP 16-channel and 32-channel digital modules. These modules provide 16 or 32 points of digital input or digital output in the same space as a 4-channel digital module. They are ideal for OEMs and for anyone who needs up to 512 digital points on a single mounting rack.

Case Study: AAQUA NV

In 2005, AAQUA NV was looking for a way to cut costs while still providing robust automated systems.

They learned about Opto 22 products and did some research. They liked what they saw.

Thirteen years and approximately 70 installations later, AAQUA NV is still exploring the possibilities of Opto 22 products and adding new features to their system.
