8414

8ch ADC+Tacho, Direct, Bridge

Overview

This card has the main features of the 8412 and includes bridge completion and transducer excitation. Each channel provides bridge completion configurations of ¼, ½ and full bridge, internal calibration shunt resistors and selectable bridge resistance of 120, 350 or 1000Ω. The 8414 has a slightly lower specification than the 8404, but provides twice the channel density. This allows a P8020 chassis to support up to 40 analog channels and two tacho channels. The flexible mutlipole connector gives these systems manageable wiring and offers the option of fast connection external boxes if desired.
