English | SNAP-IDC-32 SNAP 32-channel Digital Input Module, 10-32 VDC |
  |
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 MicroLogix or other RSLogix-based PLC system,
such as ControlLogix or CompactLogix.
For easy field wiring, use the SNAP-IDC-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 Factory Mutual approval, see the SNAP-IDC-32-FM module instead.
