Omicron CMC 430 - External interface connector; Transistor outputs (binary outputs 11-14)

3.13 External interface
The SELV interface connector EXTERNAL INTERFACE holds four additional transistor binary outputs
(binary outputs 11 ... 14). Unlike regular relay outputs, these outputs are bounce-free (small signals)
and have minimal reaction time.
In addition, two high-frequency counter inputs for up to 100 kHz are available for the testing of energy
meters.
