1.3 What is the SC Series?
The SC Series of Signal Conditioners/Indicators are versatile, multi-channel devices
designed to operate with many different types of sensors. Several different chassis
types, Input channels, and Output channels are available to allow the configuration of
an SC instrument to meet a variety of measurement and control needs. The operation
of an SC instrument is based on digital technology to provide improved accuracy,
superior ease of setup, and a wealth of features.
1.3.1 Features
The main features of the models SC1000, SC2000, SC2001 and SC3004 are:
• Four alarm limits (optional sixteen), with versatile setup (not available on Model
SC1000)
• Automatic setup, calibration, and scaling of strain-gage sensors through the use
of Signature Calibration
TM
• Field selectable, digital, low-pass filtering (“damping”) on each Input channel
• Up to ±50,000 part resolution
• Field selectable five-, six - or seven-digit (9,999,999 maximum) display
• RS-232 communications standard (RS-485 optional)
• Local or remote setup using the RS-232 or RS-485 port
• Push-button on/off tare feature
1.3.2 Chassis Models
Several models (i.e. chassis types) are available:
• SC1000: 1 to 4 physical channels, 3/8 DIN case, no limits or peak detector
• SC2000: 1 to 4 physical channels, 3/8 DIN case
• SC2001: 1 to 4 physical channels, portable case
• SC3004: 1 to 14 physical channels, 19” rack mount case, 1 to 3 quad-line displays
1.3.3 Channel Types
Channels can be one of three types: Input, Output, or Virtual
Input Channels
Input channels are hardware circuit boards with a unique channel number. Currently,
they are available for the following types of sensors:
• Strain-gage sensors, such as unamplified pressure transducers and load cells
• Sensors with voltage outputs, such as transducers with the Option 2a, 2b, 2c, 2d,
2g, 2j, 2k, 2p, 2t or 2y internal amplifier
• Sensors with current outputs, such as transducers with the Option 2j, 2k or 2n
internal amplifier
• AC-AC LVDTs (Linear Variable Displacement Transducers)
• DC-DC LVDTs
Output Channels
Output channels are hardware circuit boards with a unique channel number. They
include:
• Relay Output channels, which can add additional limits to the standard four (N/A
on Model SC1000).
• DAC Output channels, which provide additional voltage or current outputs.
Virtual Channels
Virtual channels are software based devices that occupy a channel number, but not a
physical slot, in an instrument.
• Split Display Virtual channels allow the displaying of any two channel’s track, peak
or valley values at the same time.
