Hot Plug-in
In system automatic module detection

The M1412A 8AO module provides 8 analogue outputs.
A link in the module selects all outputs to be either 020mA or 4-20mA. Reduced output current ranges can
be achieved through software scaling. The outputs are
isolated from the logic, and are powered from an
external 24Vdc supply.
The module may be inserted into any I/O slot in a

Maxiflex system.
Inputs are terminated on plug-in screw terminals.
The module can be inserted or removed while the
system is powered.
Auto-detection capability allows the CPU to recognise
the presence of this module in the system.
