PCD3.W525 analogue combined input/output module
with electrical isolation
General information
The PCD3.W525 is an analogue multi-purpose module with four inputs and four
outputs. Each input and output can be configured individually as an industry-
standard interface of type 0

20 mA. The inputs can also
be configured in such a way that they can support Pt/Ni1000 or Pt500 temperature
sensors. Various filter types and scaling ranges can also be used for the module.

Miscellaneous
●
All I/O channels are electrically isolated from the Saia PCD
®
and the external
power supply. (but all channels are electrically connected to each other).
●
Each channel has two connections.
