DI-8B Series Amplifiers

DI-8B amplifiers offer the convenience to mix and match modules based upon measurement function and range to meet any application requirement, from the most simple to the most complex. Each amplifier in the DI-8B line provides input-to-output isolation, and since one module is deployed per measured channel, channel-to-channel isolation is also guaranteed. Isolation extends measurements into application areas that non-isolated products cannot address. Examples are current measurements using shunts, grounded or powered thermocouples, and the elimination of noise caused by ground loops.
