Binary input/
output modules
Ordering no #10 Notes and rules
For pulse counting, for example kWh metering, the BIM with enhanced pulse counting capabilities must be used.
Note: 1 BIM and 1 BOM required in positions P3 and P4 in REL A42, B42 and D42. B42 requires one extra BIM in position P5. 1 IOM required in position P3 in A41.
