Component Function - ProMinent Aegis II Manual

When a Com Module is added to expansion slot #3, the dual 4-20mA
outputs acquire the identification letters I and J. These are the letter
assignments for any card installed in this slot.
If the dual 4-20mA input driver is installed onto the Com Module, it is
represented by the letters K and L.
The Dual 4-20mA input driver card is the only card that can be added
to the Com Module.
The Wiring Terminal Table shows all connections to the Com Module
