Model SCC-C/C Single Channel Module

NOTE: THIS IS A FACTORY CONFIGURED UNIT

SCC OPEN SIGNAL Family

Each SCC-C/C 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 unit may be re-configurated to accept a 0 to

20mA, 0 to 10mA, 4 to 20mA, ±10mA, or ±20mA

input signal and provide a 0 to 20mA or 4 to

20mA output signal. Unit re-configuration re-

quires Dwyer’s 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’s Instrument’s Windows®/PC or Win-

dows®/CE HPC based SC Configurator Utility,

interfacing the SCC unit to the computer’s RS-

232C comm port with an SCC Configuration Cable,

and then changing the unit’s input/output con-

figuration 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 modules 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 SCC model family permits

users to select the model which meets their unique

signal conditioning needs.

SET SCREW

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 configured to meet their unique need. All

SCC models may be configured/reconfigured by a

user at anytime through use of an optional 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 direc-

tion of the unit’s configuration parameters set by

the user (or factory) via Windows®/PC or Win-

dows®/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 +V/C IN

Negative (-) to SCC terminal -V/C IN

4. Connect output actuator/device to SCC unit:

Positive (+) to SCC terminal +OUT

Negative (-) to SCC terminal -OUT
