SNAP 32-channel Digital (Discrete) Input Module, 10-32 VDC

Production Specification

The SNAP-IDC-32 32-channel digital input module provides 32 digital input channels in one compact SNAP module. The SNAP-IDC-32 is ideal for OEMs and others who have applications with high point counts, or for those requiring large numbers of digital input 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.

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-IDC-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.

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.

This data sheet covers the following modules:

Case Study: AAQUA NV

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.
