The maximum current output on the analog outputs of the MID will be the same as the controller you connect to it. If you are using a 7344 controller, these outputs will be +/-10 volt +/-5mA outputs. If you are using the 7334 controller, these outputs will be disconnected. In any case most servos will not be able to be driven directly by these outputs unless they are used as command signals for a servo drive that can generate more current or the DC motors used can be driven with the current output capability. Bear into mind that even if you are able to control a servo directly from these outputs, you will only be able to control velocity for the motor, not position as a torque drive like the MID-7652/4 would be required for that.
