STB-TC
The STB-TC thermocouple panel provides sixteen low level
STB-TC–SPECIFICATIONS
voltage inputs or fifteen thermocouple inputs with cold junction
compensation. The range of the inputs can be set to be all +5 V,
± 100 mV, ± 50 mV, ± 25 mV, ± 10 mV or ± 5 mV range. A dip
switch is used to select a gain of 1, 50, 100, 200, 500 or 1000 to
provide these ranges. At each channel, users can also add an
8 Hz low-pass filter to block out high frequency noise, a return
path for bias currents and break detect circuitry. All these op-

User Defined
OBSOLETE functional diagram of the STB-TC is shown in Figure 4.
The STB-TC is the right solution for applications with low level
signals or thermocouples which require no electrical isolation.
The STB-TCI, or 5B02 with 5B Series signal conditioning
modules, should be used if electrical isolation is required or if a
mix of thermocouple types is to be used.
