SNAP DIGITAL INPUT MODULES
Features
Four channels per module
4,000-volt transient isolation
Convenient pluggable wiring terminals
Channel-specific LEDs
UL and CE approved
Accepts 22 to 14 AWG wire
Factory Mutual approved (part numbers ending in FM)
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.

SNAP digital input modules are compatible with all SNAP PAC brains
and rack-mounted controllers, including Wired+Wireless.
Notes for legacy hardware: These modules can also be used with
SNAP Ultimate, SNAP Ethernet, and SNAP Simple brains, and with
other SNAP brains such as the serial B3000 and the B3000HA. They
also mount on B-series, M-series, and D-series racks.
Wiring Options
For easier, faster wiring of field devices to input modules, see the SNAP
TEX Cables and Breakout Boards Data Sheet, form #1756. Each SNAP
TEX cable snaps into the top of the module and terminates at the
breakout board with 18-gauge, color-coded flying leads, already
stripped and ready for wiring. Breakout boards offer optional fusing,
fuse-blown indicators, and bussed power to loads.Specifications: AC

SNAP-IDC5-SW AND SNAP-IDC5-SW-NC MODULES
Description
The SNAP-IDC5-SW and SNAP-IDC5-SW-NC modules provide four
channels of contact status input. Each module supplies 15 volts of
power to an external dry contact switch. The SNAP-IDC5-SW senses
switch closure; the SNAP-IDC5-SW-NC senses switch opening. Each
user-supplied switch is connected with two wires. Because these
modules include power for the switch, they are particularly
cost-effective when labor costs for wiring external power are high.
Typical switches for use with these modules are switched status
sensors (level sensors, pressure indicators, etc.), magnetic reed
switches (used on doors or windows for burglar alarms), snap-action
micro switches, the auxilliary switches on motor starters, and most
relay contacts.
CAUTION: The SNAP-IDC5-SW and SNAP-IDC5-SW-NC inputs are not
intended to be used with contacts that are connected to any external
user-supplied voltage or currents.
