OPTO 22 - SNAP-IDC-32DN _ SNAP 32-channel Digital (Discrete) Input Module, -2.5 to -12 VDC, with positive common connection

Quick Specs:

SNAP 32-channel Digital (Discrete) Input Module
-2.5 to -12 VDC
with positive common connection

The SNAP-IDC-32DN 32-channel digital input module provides 32 digital input channels in one compact SNAP module. The SNAP-IDC-32DN 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.

The SNAP-IDC-32DN has an input range of -2.5 to -12 VDC, and its common connections are positive rather than negative, making it ideal for NPN or sinking type inputs.

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.

For sensing 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).

If you need a similar module with a higher input range, see the SNAP-IDC-32N.

If you need a module with negative common connections, see the SNAP-IDC-32D.
