DESCRIPTION
This data sheet covers SNAP digital input modules with four
channels. For modules with 16 or 32 channels, see form 1556, the
SNAP High-Density Digital Modules Data Sheet.
Opto 22 SNAP I/O 4-channel digital input modules are part of the
SNAP PAC System. Optical isolation on these modules provides
4,000 volts of transient (4000 V for 1 ms) protection for sensitive
control electronics from industrial field signals. Digital input
modules can sense either AC or DC signals.
All SNAP 4-channel digital modules have removable top-mounted
connectors to provide easy access for field wiring, and all operate
on 5 VDC control logic. Each digital module features integral
channel-specific LEDs for convenient troubleshooting and
maintenance. Each module is factory tested twice and is UL and CE
approved. In addition, part numbers ending in FM are Factory
Mutual approved.
SNAP input modules are used to sense the on or off status for AC or
DC voltages from such sources as proximity switches, push
buttons, or auxiliary contacts. The SNAP-IDC5G is ideal for
detecting 48 VDC in telecom applications. The SNAP-IDC5-HT is
designed for sensors that have a high leakage current.
The SNAP-IDC5-SW and SNAP-IDC5-SW-NC modules supply power
to an external dry contact switch and sense switch closure
(SNAP-IDC5-SW) or opening (SNAP-IDC5-SW-NC).
SNAP-IAC5MA and SNAP-IDC5MA feature manual-on/manual-off/
automatic switches, ideal for testing control applications. The
switches override input from field devices, so you can determine
whether a problem lies in the application or in the device.
SNAP racks use a retention rail locking system. Use two 4-40 by
½-inch standard machine screws to hold each module in position
on the SNAP rack.
