3. HARDWARE CONFIGURATION
3.1 Selection of Mounting Rack
The number of the I/O modules and CPU type must be considered when selecting the
mounting rack. If the process to be controlled is spread over a large area, considerable
savings can be achieved by using the AL2000 to implement a distributed control system
utilising several remote units. In this case only the central unit requires PLC programming,
the remote units operate as Modbus RTU I/O units only.
Five different mounting racks are available:
1. MR3-mini for up to 3 I/O modules (CPU2000SCP)
2. MR3 for up to 3 I/O modules
3. MR5 for up to 5 I/O modules
4. MR11 for up to 11 I/O modules
5. MR16 for up to 16 I/O modules

3.2 Selection of Power Input Module(s)
The AL2000 power supply is made up of two separate parts, the power connecting module
and the power supply module. All mounting racks except the MR3 and MR3-mini
must be fitted with both of these units. A different, single-unit power supply is included
with the MR3 and the MR3-mini requires no power supply (the CPU2000SCP has its own
power supply).
There are two types of power connecting module available, the PCON230 and the
PCON24. These must be used in conjunction with the POWAC and POWDC power supply
modules respectively:
PCON230 and POWAC: Input voltage 230VAC
Suitable for MR5, MR11, MR16
PCON24 and POWDC: Input voltage 24VAC/DC
Suitable for MR5
PWR3: Input voltage 230VAC or 24VAC/DC
Suitable for MR3 only
