Place a 0.02µF capacitor across In+ and Ex+ on channels containing DI-8B42-01 modules
WinDaq displays values that are not consistent with the input on channels containing DI-8B42-01 modules.
A design issue involving the DI-8B42 module that can cause the amplifier to oscillate when used with certain types of transmitters.
To resolve these issues follow the steps below.
Place a 0.02µF capacitor across In+ and Ex+ on channels containing DI-8B42-01 modules.
Place the capacitor as shown below:
DI-718B(x), DI-788 and DI-78B input expanders containing DI-8B42-01 modules.
