Dwyer Series SCC Instruction Manual
SCC OPEN SIGNAL Family
Model SCC-C/V Single Channel Module
NOTE: THIS IS A FACTORY CONFIGURED UNIT
FACTORY CONFIGURATION
SCC models may be purchased with a factory preset configuration for plug-n-play application or
custom onfigured to meet their unique need. All
SCC models may be configured/reconfigured by a
user at anytime through use of an optional SC Configuration Package.
Each SCC-C/V unit is configured and calibrated at
the factory for the input signal range and voltage
output range printed by the factory on the SCC
unit’s side-label.
The above input signal range is ONE of FIVE
ranges the unit is capable of accommodating.. The
unit provides a 0 to 5V, 1 to 5V, 0 to 10V, ±5V, or
±10V output signal. Unit re-configuration requires
SC Configuration Utility.
Theory of Operation - An analog world input signal
arriving at the SCC unit is isolated, filtered, amplified, scaled and/or linearized (as required) by the
units onboard microprocessor under the direction
of the unit’s configuration parameters set by the
user (or factory) via Windows®/PC or Windows®/
CE HPC (Handheld Personal Computer) based SC
Configurator Utility.
This SCC unit may be reconfigured by a user at
any time via their personal computer (PC) or
handheld personal computer (HPC) by installing
Dwyer Instrument’s Windows®/PC or Windows®/
CE HPC based SC Configurator Utility, interfacing the SCC unit to the computer’s RS-232C
comm port with an MSF Configuration Cable, and
then changing the unit’s input/output configuration settings.
The conditioned signal is then converted to a high
level analog current or voltage output signal (depending upon model) and presented at the unit’s
isolated output.
REQUIREMENTS
Mandatory:
• 15 - 32VDC, 30mA external supply voltage
Optional:
• SC Configuration Package (Part No. SCCCC-A1)
Package consists of: SC
Configurator Utility and SCC Configuration Cable.
OPERATIONAL DESCRIPTION
The SCC family of single channel signal conditioning and isolating modues are intelligent, user
programmable, high-accuracy, user friendly, signal conditioning units.
INSTALLATION
Each SCC model supports one (1) specific analog
signal-type on its input channel and outputs one
(1) high-level current or voltage signal depending
upon model. A diverse MSC model family permits users to select the model which meets their
unique signal conditioning needs.
1. Mount SCC unit on standard TS32 or TS35
DIN rail.
2. See wiring diagram on reverse side. Connect
external 15 to 32VDC power source to SCC

DIAGNOSTIC TOOLS
Two LEDs one RED and one GREEN are located
on the front face of the SCC’s enclosure and provide user with visual indication as to unit operation.
LED FUNCTIONALITY
LED’s have three operational states:
Steady ON
Steady OFF
Blinking
Condition: GREEN = BLINKING
RED = Steady OFF
Meaning: Module is processing data.
Condition: GREEN = Steady ON
RED = Steady ON
Meaning:
1) Configuration data is not loaded in
module memory. -OR- 2) During module re-configuration both LED’s are normally ON indicating data is being properly transferred to or from
module memory.
Condition: GREEN = BLINKING
RED = BLINKING
Meaning:
The measured input signal is outside
the modules configured range. When the signal is
within configured range the LED’s indicate normal operation.
All other combinations indicate the module is not
operating correctly.
This unit is protected against
abnormally high and low voltages. Marginally low voltages, marginally high voltages
and power fluctuations for extended periods of
time can cause permanent damage.

WARRANTY -- Manufacturer (Dwyer Instruments, Inc.) warrants that its product, under
normal use and specified use, is free from defects and poor workmanship for a period of
twelve (12) months from the date of shipment from the Dwyer Instruments, Inc. factory.
Dwyer Instruments, Inc. makes no other warranties or representations express or implied,
whether of merchantability, suitability of fitness for a particular purpose or otherwise
Dwyer Instruments, Inc. quality products were designed, and are manufactured with tight
tolerance specifications. Any attempt to repair or otherwise modify Dwyer Instruments,
Inc. products will result in the termination of all warranty benefits. Although Dwyer
Instruments, Inc. may choose to repair a product returned under warranty, it will not attempt

F.C.C. STATEMENT -- This equipment has been tested and found to comply with the
limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference in a residential
installation. This equipment generates, uses and can radiate radio frequency energy and,
if into installed and used in accordance with the instructions, may cause harmful interference
to radio communications. However, there is no guarantee that interference will not occur
in a particular installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on, the user
is encouraged to correct the interference by one or more of the following measures: (1)
Reorient or relocate the receiving antenna; (2) Increase the separation between the
equipment and receiver; (3) Connect the equipment into an outlet on a circuit difference from
that to which the receiver is connected; (4) Consult the dealer or an experienced radio/TV
technician for help.
An SCC’s configuration can only be changed
through use of a personal computer running our
Windows®based SC Configurator Utility and a
special configuration communication cable to
interface the SCC unit and personal computer
together. (See Requirements - on reverse side for
