Model SCC-C/V Single Channel Module
NOTE: THIS IS A FACTORY CONFIGURED UNIT
SCC OPEN SIGNAL Family
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.
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, interfac-
ing the SCC unit to the computer’s RS-232C
comm port with an MSF Configuration Cable, and
then changing the unit’s input/output configura-
tion settings.
FACTORY CONFIGURATION
• 15 - 32VDC, 30mA external supply voltage
Mandatory:
Optional:
• SC Configuration Package (Part No. SCC-
CC-A1) Package consists of: SC
Configurator Utility and SCC Configura-
tion Cable.
REQUIREMENTS
The SCC family of single channel signal condi-
tioning and isolating modues are intelligent, user
programmable, high-accuracy, user friendly, sig-
nal conditioning units.
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 per-
mits 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
unit:
Positive (+) to SCC terminal +VDC
Negative (-) to SCC terminal -VDC
DIAGNOSTIC TOOLS
Two LEDs one RED and one GREEN are located
on the front face of the SCC’s enclosure and pro-
vide user with visual indication as to unit opera-
tion.
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-con-
figuration both LED’s are normally ON indicat-
ing 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 nor-
mal operation.
All other combinations indicate the module is not
operating correctly.
SCC models may be purchased with a factory pre-
set 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 Con-
figuration Package.
Theory of Operation - An analog world input signal
arriving at the SCC unit is isolated, filtered, ampli-
fied, 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.
The conditioned signal is then converted to a high
level analog current or voltage output signal (de-
pending upon model) and presented at the unit’s
isolated output.
3. Connect input current device to SCC unit:
Positive (+) to SCC terminal +C/V IN
Negative (-) to SCC terminal -C/V IN
4. Connect output actuator/device to SCC unit:
Positive (+) to SCC terminal +OUT
Negative (-) to SCC terminal -OUT
