5B38 Strain-Gauge Input Module
The 5B38 strain-gauge input module features a bandwidth of 10 kHz. The
5B38 accepts input signals from full- and half-bridge 300
Ω
to 10 k
Ω
transducers. The 5B38 also provides a +10 V excitation and produces an
output signal of –5 to +5 V that is routed from the SC-2311 to the E Series
DAQ device for measurement.
You can insert and use the 5B38 strain-gauge input modules in any of the
eight 5B channels inside the SC-2311.
5B42 Process Current Input Module with 20 VDC Loop
The 5B42 process current input module interfaces with 2-wire transmitters
and provides an isolated, regulated 20 V supply for current measurement.
The module filters and amplifies the 4–20 mA process-current input to
produce an accurately scaled, low-noise, low-impedance output of +1 to
+5 V or +2 to +10 V.
You can insert and use the 5B42 process current input modules in any of the
eight 5B channels inside the SC-2311.
5B45/46 Frequency Input Module
The 5B45 frequency input modules accept full-scale frequency signals
ranging from 500 Hz to 20 kHz. The 5B46 frequency input modules accept
full-scale frequency signals from 20 kHz to 275 kHz. Each module scales
the frequency input to a 0–5 V output signal that is routed from the
SC-2311 to the DAQ device for measurement.
You can insert and use the 5B45/46 frequency input modules in any of the
eight 5B channels inside the SC-2311.
