Smart Line Home
Smart Line is a new series of signal conditioning modules with the following design philosophy
- Smaller case style.
- Has a wide range ac/dc power supply.
- Capable of changing ranges and settings without using test equipment or opening the case.
- Simple setup and verification process.
- No trim pots.
We also wanted to have the option of;
- Display of process variables and graph of real time data.
- Able to create special calibrations and functions without affecting standard ranges.

The SL300 PC Programmer
This free tool is upgraded with each release of a SL series module. More information on the SL300 PC Programmer is available here. When used with the SL332/SL335 it can set functions that are not available using the top mounted switches. The SL300 Programmer can read and program all parameters for the entire range of Smart Line signal conditioners.
SL332 Additionl Functions
SL332 has extra features not documented on the data sheet as follows;
Output Full Scale Check
While input code switch is in position 0 the output will go to full scale of the range selected on the output code switch. The output full scale value for each setting is found on the data sheet.
Remote Control Output
The output can be remotely controlled by the SL300 module when the input switch is set to F and the output switch is set to D.
The customised output range has signal limiting that can be set using the SL300. This signal limiting is only in effect on the customised range (input and output switches on F) and if it has been enabled by the SL300.
SL335 Additionl Functions
SL335 has extra features not documented on the data sheet as follows;
Output Full Scale Check
While input code switch is in position 0 the outputs will go to full scale of the range selected on the output code switches. The output full scale value for each setting is found on the data sheet.
Remote Control Output
When the input switch is set to F and the output switches are set to to D both outputs are remotely controlled.
When the input switch is set to F, output 1 is set to F and output 2 is set to D then output 1 follows the input and output 2 is remotely controlled.
The customised output ranges have individual signal limits. This signal limits are in effect on the customised ranges.
SL339 A cheaper isolator with more features.
The SL339-20 is essentially a SL332-22 without the range selection switches fitted. This has the effect of reducing the purchase price of the unit.
The unit is user configurable using the SL300 configuration software with no compromises on measurement accuracy and speed. The SL339-20 packs advanced custom linearisation, signal limiting and direct reverse action into a thin 12.4mm case.

SL340 A Better Universal Isolator
Back in 1999 APCS invented the term Universal Signal Conditioner with the USC701. The unit was designed to replace all other transmitter types so a company could have one unit on the shelf to that could be programmed for the desired function before fitting.
In the market today there are many isolators that claim to have a universal input and cover many mV and temperature ranges.
In many cases these units work well on the specified ranges but when customising the ranges they may suffer from reduced range within the analogue to digital converter on the input or reduced use of the digital to analogue converter on the output. As a result the quoted accuracy will be reduced.
The SL340 has not been designed to replace the USC701. Today's market requires cheaper isolators and converters that use less power and space. The SL340 represents what the market wants at a completive price.
The SL340 with only four input terminals supports Thermocouple, RTD, Strain Gauge, Resistance, Slide Wire and mV inputs without compromising accuracy.
The programmable input current and voltage sources each have two distinct ranges to maintain accuracy.
The input instrumentation amplifier can be configured as single ended or differential depending on the application. This amplifier has programmable offsets to ensure that the analogue to digital converter is always working over the widest possible range for the user's input calibration.
Measurements are processed by the input side CPU, this dedicated processing ensures fast conversion to a digital signal that represents the user's specified input calibration. This digital signal has been corrected to remove standard linearity errors produced by the sensor currently in use (TC, RTD, etc).
A digital data is sent from input to output via an an optical isolator. The output CPU contains an integrated digital to analogue converter and controls the switching of the output range components.
As isolation and output drive method does not rely on pulse width modulation conversion or linear conversion conversion methods no additional linearity and accuracy errors are introduced for a wide range of user defined calibrations.
