Overview
The DBK42 allows LogBook or Daq device systems to work with up to 16 5B signal conditioning
modules. Modules are available for various signal types (e.g., low-level thermocouple signals, strain-gage
signals, etc). The DBK42 offers 500 V isolation from the system and between channels. The DBK42 is
compatible with all 5B output modules, and the configuration is very flexible. You can select the type of
signal attached to each channel.
An accessory cable connects the DBK42’s output to the P1 analog input connector. One LogBook or Daq
device can support up to 16 DBK42 units with a maximum of 256 isolated analog input channels. The
LogBook or Daq device scans the DBK42 channels at the same 10 µs/channel rate as other DBKs (256
scans in 2.56 ms in a full system).
The DBK42 can obtain power from an included AC adapter, an optional DBK30A rechargeable battery
module, or directly from a 12 VDC source (such as a car battery). The built-in power supply can serve a
fully-configured system using bridge excitation.
For DaqBoard/2000 Series applications, DBK42 is typically powered from an included AC adapter. The
unit’s built in power supply can serve a fully-configured system using bridge excitation.
