SNAP Digital Input Modules
SNAP Digital Input Modules
Description
Opto 22 SNAP I/O 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 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
