DESCRIPTION
SNAP TEX cables and breakout boards are part of the SNAP TEX family
of wiring and mounting accessories. (See form 1772 for accessories
not covered in this data sheet.) These cables and boards save time
and expense during installation, maintenance, and debugging by
reducing the time and effort required to wire field devices to SNAP I/O
modules.
Choose the cables and breakout boards for your modules based on
the table that starts on page 2. Specifications and dimensions begin
on page 5 and wiring diagrams on page 24. Assembly and installation
steps are on page 10.

SNAP TEX Family
SNAP TEX cables provide convenient connections from I/O modules
to field wiring. Most cables are designed to connect to breakout
boards; some cables have flying leads for direct connection to field
devices.
SNAP TEX breakout boards move terminals away from the crowded
rack area for easier installation and maintenance. Most boards can be
panel mounted or DIN-rail mounted (see page 10). See compatibility
tables starting on page 2.

These three cables provide neat, protected wiring from the top of a 1-,
2-, or 4-point module to the breakout board. Each cable snaps into the
top of one module and terminates at the breakout board with
18-gauge, color-coded flying leads, already stripped and tinned and
ready for wiring. The leads attach easily to the breakout board with
spring connectors.
SNAP-TEX-CBO6—Odd-numbered terminals are commoned.
SNAP-TEX-CBE6—Even-numbered terminals are commoned.
SNAP-TEX-CBS6—No common terminals; wiring is straight through.
See the tables starting on page 2 to determine the correct cable for
your module and breakout board.
This photo shows the contrast between a regularly wired
SNAP PAC rack (at upper left) and one using SNAP-TEX-CBE6,
-CBO6, and -CBS6 cables (at lower right).
The cables protect top-of-module connections and wires,
and make it easier to follow wiring to field devices.

CABLES TO CONNECT G4 TO SNAP: SNAP-HD-G4F6, SNAP-HD-G4F6N
The SNAP-HD-G4F6 and cables are used to connect a SNAP
high-density digital (HDD) module to G4 mounting racks in order to
integrate older G4 (or even G1) digital output systems with modern
PAC Project software and SNAP PAC Ethernet-based controllers.
Each cable connects two 16-channel mounting racks to one 32-point
digital module. Cables can also be used to connect G1 mounting
racks with header connectors to these modules. See the table below
for module and rack compatibility.
DA T A SHEET
Form 1756-200206
PAGE 9
For outputs, this connection makes available the G4 output’s up to
3-amp switching and sensing capability, which can provide twelve
times the 0.25 amp capability of the HDD modules themselves. (For
G4 module specs, see Opto 22 form #727, the G4 Digital I/O Data
Book.)
NOTE: For another option, see the SNAP-UDC-HDB-G4 on page 20.
The SNAP-HD-G4F6 cable can also be used to connect two
SNAP-TEX-MR10-16C breakout boards to one 32-point digital module.
See “Breakout Boards with Mechanical Relays: SNAP-TEX-MR10-4,
SNAP-TEX-MR10-16, and SNAP-TEX-MR10-16C” on page 13.
For more information on HDD modules, see the SNAP High-Density
Digital Module Data Sheet (form 1556).

NOTE: While not designed for this use, it is possible to connect the SNAP-IDC-32 module with G4 15 or 24 V inputs using a SNAP-HD-G4F6 cable.
However, the SNAP-IDC-32 uses positive-true logic and therefore returns the inverse of the typical negative-true logic. For example, if the SNAP-IDC-32
is controlled by a PAC Control strategy, an “OFF” state from it actually indicates that the associated G4 module is turned ON.

BREAKOUT BOARDS: SNAP-TEX-32, SNAP-TEX-FB16-H, SNAP-TEX-FB16-L
DA T A SHEET
Form 1756-200206
PAGE 11
The SNAP-TEX-32 is a simple breakout board with straight-through
wiring. Designed primarily for 2- and 4-point analog inputs/outputs
and for 4-point digital inputs, the breakout board is used with
CAUTION: Odd pins on the SNAP-TEX-FB16-H and SNAP-TEX-FB16-L
breakout boards are commoned. Use only straight-through or odd cables
with these boards.
SNAP-TEX cables. The board can be used with digital outputs, but it
does not have fuses.
The SNAP-TEX-32 can also be used with 8-, 16-, or 32-point SNAP
analog modules (not thermocouples). See the table beginning on
page 2 for recommended cable and board combinations for your
modules.
The SNAP-TEX-FB16-H and SNAP-TEX-FB16-L breakout boards
provide a fuse and a fuse-blown indicator for each of their 16
channels. In addition, they provide power to loads: the
SNAP-TEX-F16-H provides 120–240 volts, and the SNAP-TEX-F16-L
provides 12–24 volts. Simply attach the power source to a single spot
in the middle of the rack, and power goes out to solenoids or
switches, depending on the module you’re using. These breakout
boards are used primarily for digital inputs and outputs.

BREAKOUT BOARDS WITH MECHANICAL RELAYS: SNAP-TEX-MR10-4, SNAP-TEX-MR10-16,
AND SNAP-TEX-MR10-16C
The SNAP-TEX-MR10-4, SNAP-TEX-MR10-16, and SNAP-TEX-MR10-16C
breakout boards, designed for high-current switching, feature mechanical
relays that can switch up to 10 A per channel. (Standard SNAP output modules
can switch up to 0.75 A; SNAP-OMR6 output modules can switch up to 6 A.)
These breakout boards include on/off indicators for each channel,
and each channel can be wired for normally closed or normally open.
The boards require 24 VDC power. A replacement relay is available:
part number SNAP-MR10.
NOTE: Transient protection must be used on inductive loads.
SNAP-TEX-MR10-4
SNAP-TEX-MR10-16C
With the SNAP-TEX-MR10-16C, you can connect digital output
modules in two ways:
• Connect four standard 4-point ODC modules using the two
spring connectors and the appropriate cable for the modules
(see page 30).
• Connect one SNAP-ODC-32-SRC high-density module to the
header connectors on two MR10-16C breakout boards. Requires
a SNAP-HD-G4F6 cable (see page 50).
Also, bussed commons in 2-channel groups provide easier wiring
of loads. Bussing straps (STRAP2Q and STRAP4Q) can be used for
quick common power connections between relay groups (see
page 31).
