Customized I/O options
mini CORI-FLOW ML120
instruments offer several customized input/output functions through pin 5 of the M12 connector
as an option. The required I/O options are factory installed as specified at ordering time, and cannot be changed manually.
The possible configurations are described in the table below. See the hook-up diagram for custom bus and I/O
configurations (document 9.16.118) for an explanation of the codes.

Disabled, pin 5 is pulled down to 0 Vdc (default selection)
A1V
0…10 Vdc sourcing output, controller
Analog signal for pump or external valve steering (control signal only).
When the controller output is used for pump or external valve steering (only applicable to mass flow
meters with the controller function enabled), make sure to set parameter
Valve maximum
to 0.3 [A]. For mass
flow controllers, the controller output signal represents the valve actuator current. This output is limited to
a value below 10 Vdc, due to the maximum valve current restriction.
