By combining the terminal block signal conversion adapter with base unit BUM7B, an
I/O module (G3 I/O) can be upgraded to the G2 I/O module using the internal wiring up
to the I/O module (G3 I/O) terminal block of the existing T3/T3H.
The G3 I/O terminal block is connected to the G2 I/O by mounting the terminal block
signal conversion adapter on BUM7B as shown in the photo below.
The photo shows BUM7B and terminal block signal conversion adapter connected with
the G3 I/O terminal block.
