SNAP High-Density Digital I/O Modules Features SNAP-IDC-32 high-density digital input module Description SNAP high-density digital (HDD) modules from Opto 22 provide 16 or 32 digital input or output points in one compact SNAP module. All HDD modules work with the SNAP PAC System, which consists of SNAP PAC controllers and brains, SNAP PAC racks, SNAP I/O modules, and PAC Project software. These modules can also be used in intelligent remote I/O for Allen-Bradley® Logix PLC systems. SNAP high-density digital modules are ideal for OEMs and for anyone who has high point-count applications. The highdensity point 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.

DATA SHEET The following high-density digital modules are available: • The SNAP-IDC-32 or SNAP-IDC-32-FM digital input module, with 32 input points, can be used to sense on/ off status for 10–32 VDC inputs from sources such as proximity switches, limit switches, push buttons, and pilot switches (PNP or sourcing type). • The SNAP-IDC-32N is similar, but its input range is -10 to -32 VDC and its common connections are positive rather than negative, making it ideal for NPN or sinking type inputs. • The SNAP-IDC-32D has an input range of 2.5 to 12 VDC. • The SNAP-IDC-32DN offers a -2.5 to -12 VDC input range and has positive common connections, also suited to NPN (sinking) inputs. • The SNAP-IDC-16 digital input module offers 16 points with channel-to-channel isolation. It can sense on/off status for 10–32 VDC/VAC loads. • The SNAP-IDC-HT-16 leakage tolerant digital input module is used with proximity switches. It offers channel-to-channel isolation for 16 points and senses on/off status for loads of 15–28 VDC/VAC.

SNAP High-Density Digital I/O Modules • SNAP High-Density Digital I/O Modules SNAP-IAC-16, SNAP-IAC-A-16, and SNAP-IAC-K-16 digital input modules each have 16 points with channelto-channel isolation. These modules sense on/off status for 90–140 VAC (SNAP-IAC-16), 180–280 VAC (SNAP-IACA-16), or 70–130 VAC (SNAP-IAC-K-16). SNAP-ODC-32-SRC, SNAP-ODC-32-SRC-FM, SNAPODC-32-SNK, and SNAP-ODC-32-SNK-FM digital output modules have 32 points and can switch on and off 5–60 VDC loads, either sourcing or sinking. Part numbers ending in -FM are Factory Mutual approved. All HDD input modules feature...

SNAP High-Density Digital I/O Modules terminal. The OptoTerminal-G20 displays the status of a highdensity digital module’s points on a two-line LCD display and can also be used to turn output points on and off. See Opto 22 form 1547, the SNAP High-Density Digital Modules User’s Guide, for more information. These HDD modules and cables also work with some G1 racks, and the SNAP-HD-G4F6 works with some integrated I/O racks. For more information, see form #1756, the SNAP TEX Cables and Breakout Boards Data Sheet. Outputs Connect SNAP-ODC-32-SNK digital output modules to G4PB16H and G4PB16HC...
