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.
