How do I get 4-20mA analog inputs on my TM221C24R?

Issue:
I need 4-20mA current inputs on my TM221C24R.

Product Line:
M221 SoMachine Basic

Environment:
This applies to all TM221Cxxxx controllers. Does not apply to M221 Book controllers.

Resolution:
You can add an analog cartridge, part number TMC2AI2, to the TM221C24R.
This will give you two analog inputs that can be configured for 0-10V, 0-20mA or 4-20mA.
The embedded analog inputs on the TM221Cxxxx controllers are 0-10V only.
