Expansion I/O
EVM32-II I/O modules (or “bricks”) are sold as accessories to the Gem6K. The
EVM32-II provides more I/O than the Gem6K offers onboard. Up to eight DIN-
rail mountable EVM32-II bricks can be connected in a serial chain to the Gem6K.
Each EVM32-II brick can hold from one to four I/O SIM boards in any combina-
tion (each SIM board provides eight I/O points, for a total of 32 I/O points per
I/O brick.)
NOTE: Instructions in this section also apply to the EVM32.
EVM32-II Connection Instructions
CAUTION
Remove power to the Gem6K and the EVM32-II baseboard before:
• Installing or removing SIM boards on the EVM32-II baseboard
• Connecting or disconnecting the EVM32-II baseboard to the Gem6K or to
other EVM32-II units
• Connecting inputs and outputs to the EVM32-II
Connect EVM32-II modules to the Gem6K’s
