What is the max amps for the Adam 6050 module
I got an answer from the ADAM technical support staff:

Hello,

Referring to the General (power input) section of the datasheet.

Any power supply that provides 24VDC will be fine as long as it delivers at least 2 watts (about 1/10 of a amp).  More watts/amps are fine, the ADAM only uses what it needs.

(the DO channels are not sourcing, so you aren’t going to get an output of any voltage.  As they are sinking outputs, the voltage/amps run to the remote device and the negative leg connects back to the ADAM DO channel.  This you do have to be careful of, more than 100mA through the DO channel will damage it)
