382 Plug-In Assembly Configuration1 OPTION 0201I 1 -@Relay Multiplexer AssemblyWith ThermocoupleCompensationd, The relay multiplexer assembly with thermocouple compensation can be used forvoltage, temperature and resistance measurements, but is primarily used with ther-mocouples for temperature measurements. The assembly consists of a relay card anda terminal card. The terminal card, which can be disconnected from the relay card,has temperature compensation circuits for thermocouple measurements.DescriptionThe Option 020 assembly uses the same relay multiplexer card as the Option 010assembly, but adds a special isothermal connector block on the terminal card toeliminate unwanted measurement errors when measuring thermocouple voltages.Both hardware and software thermocouple compensation techniques are available.Hardware compensation can be used to measure the inputs of up to 20 ther-mocouples per assembly, but is limited to one thermocouple type per assembly. Softwarecompensation can be used to measure the outputs of up to 19 thermocouples,with any mixture of thermocouples.You can use the Option 020 assembly with hardware compensation to measure theoutput of up to 20 B, E, J, K, R, S or T type thermocouples (one type per assembly).You can use the assembly with software compensation to measure the output ofup to 19 thermocouples (any mixture of these types).In addition, with appropriate computer programs, you can use software compensationto determine the temperature measured by specially designed thermocouples.Artisan Technology Group - Quality Instrumentation ...
