OPTO 22 – SNAP-IDC-16 _ SNAP Isolated 16-pt Digital (Discrete) Input Module, 10-32 VDC
OPTO 22 – SNAP-IDC-16 _ SNAP Isolated 16-pt Digital (Discrete) Input Module, 10-32 VDC
Quick Specs:
- SNAP Isolated 16-pt Digital (Discrete) Input Module
- 10-32 VDC
The SNAP-IDC-16 provides 16 isolated channels of 10-32 VDC input and features automatic counting and latching. It 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.
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 field wiring, use the SNAP-HD-ACF6 wiring harness assembly with flying leads.
If you don’t need channel-to-channel isolation, see the 32-channel SNAP-IDC-32 module.
This module cannot be used with legacy brains.
