2-Wire Current Transducer
10.2.10. D8 Wiring
Each discrete I/O point on the D8 expansion module is individually configurable in software as
an input or output. Since there is just one input common and one output common, all inputs
must be the same polarity, and all outputs must be the same polarity, but inputs need not be
the same polarity as outputs, that is, outputs can switch high side or low side, and inputs can
be active high or low.
Inputs and outputs are 24Vdc rated, and optically isolated from controller. Since all inputs
share a common connection, there is no isolation between input points. By the same token, all
outputs share a common pin and therefore do not have isolation between outputs.
Wire clamp screws must be tightened to max 7 b-in (0.8Nm).
