Figure 534:
Binary in/out module (IOM), input contacts named XA corresponds to
rear position X31, X41, and so on, and output contacts named XB to
rear position X32, X42, and so on
The binary input/output module version with MOV protected contacts can for
example be used in applications where breaking high inductive load would cause
excessive wear of the contacts.
The test voltage across open contact is lower for this version of the
binary input/output module.
