Manual states "The input and output channels of the [c]FP-AIO-610 are not electrically isolated from each other". I assume this means that the commons on the input channels are connected and the commons for the output channels are connected but it does not mean that all channels on the module are connected. Is this correct? I intend to monitor two self-powered 4-20mA signals coming from a single instrument and also send two voltage signals to a different instrument. Any advice is greatly appreciated. Thanks!
