Pacific Instruments has released 6160, which is a two-channel transducer amplifier-filter module.  Each channel has isolated input and excitation, 50 kHz bandwidth and two outputs that can be filtered or wideband. Bandwidth of 100 kHz is optional.

The series 6100 mainframe holds 32 channels, which is expandable to 1024 channels using slave enclosures. 6160 is available with RS-232, IEEE-488, USB or Ethernet interface and software for Windows 2000 and XP.

The bridge input is ten-wire shielded; input (2), excitation (2), sense (2) and shunt calibration (4) with programmable constant voltage or constant current excitation. Programmable bridge completion eliminates plug-in jumpers, loose resistors and component soldering. Automatic bridge balancing ahead of the instrumentation amplifier accommodates large unbalances without limiting gain or dynamic range.

The input and excitation are isolated from the outputs, power and control interface. This gives the user complete freedom to ground the input transducer without creating ground loops that introduce noise and offset errors. The isolation provides for operation with up to ±300 Volts of common mode applied to the input.
