SNAP 32-channel Digital (Discrete) Input Module, 2.5 to 12 VDC
Data Sheet

Production Specification

The SNAP-IDC-32D digital input module, with 32 input points, can be used to sense on/off status for 2.5 to 12 VDC inputs from sources such as proximity switches, limit switches, push buttons, and pilot switches (PNP or sourcing type).

SNAP high-density digital modules are ideal for OEMs and for anyone who has high point-count applications.

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.

If you need a similar module with a higher input range (10-32 VDC), see the SNAP-IDC-32 module instead.

For NPN (sinking) inputs, see the SNAP-IDC-32DN module, which has positive common connections.

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:

The data sheet also covers the following accessories used with SNAP HDD modules:
