Notes on Wiring Diagram
The current sources are supplied by the user ( fusing is at the discretion of the user.)
A shielded cables must be used. In noisy environments twisted shielded cable is recommended. Shielded cable should have a shield tied to earth ground near the
signal source end.
Unused inputs may cause the activation of the F LED. To avoid this occurrence the unused channels should be configured in the 0 … 25 mA range.
The maximum channel to channel working voltage cannot exceed 30 VDC.
N/C = Not connected
When field wiring the I/O module, the maximum wire size that should be used is1-14 AWG or 2-16 AWG; the minimum size is 20 AWG.
