Disconnect-Style Interposing I/O Terminals,
Wiring for Modules with Two Groups per Row
This wiring format generally applies when the associated VersaMax module provides for
connection of I/O in 8-point groups. An example of such a module is the VersaMax
24VDC 16pt Input Module, IC200MDL640:
1 2 3 4 5 6 7 8 9 11 12 13 14 15 16 17 1810
I1 I2 I3 I4 I5 I6 I7 I8 I9 I10 11 I12 I13 I14 I15 I16

When connecting the Interposing Disconnect bases in this format, follow these guidelines:
Connect field devices to A1-A16 (or B1-B16 where appropriate)
Connect return wires of field devices to the corresponding common connections – A1
to W1, A2 to W2, A9 to X1, A10 to X2, etc.
Connect jumpers between the A17, W, and X terminals (or B17, Y, and Z).
Connect power supply between A17 and W (or B17 and Y).
Connect power supply between A18 and X (or B18 and Z).
