7.- EXPANSION MODULES
The unit has following expansion modules that can be connected to it.
The modules are:
   Transistor Digital Inputs/Outputs (M-CVM-AB-8I-8OTR), 
   Relay Digital Inputs/Outputs (M-CVM-AB-8I-8OR)
   Analogue Inputs/Outputs (M-CVM-AB-4AI-8AO)
   Modbus TCP Bridge communications module (M-CVM-AB-Modbus-TCP(Bridge))
   LonWorks communications module (M-CVM-AB-LON)
   Probus communications module (M-CVM-AB-Probus)
   MBus communications module (M-CVM-AB-MBus)
   Data storage module  (M-CVM-AB-Datalogger)
   Modbus TCP Switch communications module (M-CVM-AB-Modbus-TCP(Switch))
The unit accepts a maximum of 4 expansion modules. 
Depending on the modules connected, total consumption will not exceed 15W.
The unit only accepts one communications module of each type.
 
7.1.- INSTALLATION
Before installing the expansion module the device must be unplugged from all 
power supplies, both the unit's and the measurement system's internal power 
supply. 
If more than one expansion module is installed, they must be ordered by 
serial number, i.e., the module with the lowest serial number must be the 
rst installed in the unit.
