The Daughter Board concept is a one of the key features which give the Motion Coordinator system enormous flexibility in its configuration.
The Daughter Boards provide the interface to many types of Servo or Stepper Axes, plus a number of advanced communications options as well.

The number of daughter boards which may be fitted is dependant on the controller type.
The MC224 master units can hold up to 4 daughter boards in any combination. Up to 12 further daughter boards can be connected using optional Axis Expander units (4 daughter boards per unit).
Communication Daughter Boards P225, P291, P292, P293, P295, P296, P297 and P298 can only be fitted in the master unit.
The Euro 205x and Euro 209 has a single daughter board slot which can be used to provide extra axes on board.
The MC206X can use a single daughter board to provide a sixth axis in addition to the five axes (maximum) which are available on the standard controller.
The MC464 does not use the daughter board concept but uses expansion modules.
Note:
For volume/OEM applications, Trio can produce custom daughter boards for specific customer applications where required.
