PCD2.W525 has to be supplied externally! This power supply is galvanically iso- lated to both, the Saia PCD® and the I/Os of W525. Furthermore, the design allows using the same power supply for the Saia PCD® and for W525 without loosing the galvanic isolation. These schematics show the different zones of isolation:TimingInputsInternally, W525 finishes acquiring every 2 ms a new value for every input channelThis value is always ready to be read by the Saia PCD®.Dependent on the Saia PCD® speed, the transmission time of a single 16-Bit scaled value (of a single input channel) takes typically 100 μs (on a PCD2.M480) or 600μs (on a PCD2.M170)OutputsInternally, W525 outputs the last received output value from Saia PCD® with a maximum delay of 2 ms.Dependent on the Saia PCD® speed, the transmission time of a single 16-Bit scaled output value takes typically 100 μs (on a PCD2.M480) or 600 μs (on a PCD2.M170).FilterInputs
