Expansion Transmitter Module
Expansion Rack Attachment
The Expansion Transmitter installs on a DIN rail and attaches to the left side of
a VersaMax CPU or NIU module on the same DIN rail. The Expansion
Transmitter connects to up to seven Expansion Receiver Modules in expansion
"racks". The maximum overall length of the expansion cable depends on which
type of Expansion Receiver is used:
15M with any
IC200ERM002 ERMs
750M with all
IC200ERM001 ERMs
Cable Length and Data Rate
By default, the module is set up to operate with the maximum length expansion
cable at the default data rate of 250Kbits/second. If the total length of the
expansion cable is less than 250 m and there are no non-isolated Expansion
Receivers (IC200ERM002) in the expansion system, the VersaMax PLC
programmer allows the data rate to be configured to 1Mbit/second. In an NIU
I/O Station, the data rate cannot be changed from the default 250Kbits.
Terminator Plug
The last Expansion Receiver in the chain must be terminated with terminator
plug IC200ACC201 (included with the Expansion Transmitter). Spare
Terminator Plugs may also be purchased separately as part number
IC200ACC201 (qty 2).
