where:
IN1, IN2, IN3, IN4 are the pulse input terminals;
M are the pulse input terminals connected to the interface common;
M-BUS is the I/O for connection with the M-Bus line (any wiring connection sequence is allowed);
NPN transistor symbol is the pulse output;
NC is spare, i.e. not used in the given module version.
7.1.2. Interface technical parameters
The table below shows the technical parameters of individual interface blocks
Interface parameters
Enclosure
