Expansions
PLC300 | 6-1
6 EXPANSIONS
Up to two expansions can be connected to the PLC300. These expansions are the I/O type
of the CFW11 (Frequency Inverter WEG 11). The detection of the expansions is automatic
and the status of the I/Os can be checked by pressing SETUP and browsing with the
arrows <> and <>.
Address of the I/Os of the expansions
The digital and analog inputs and outputs of the expansions have fixed physical address
ranges, according to the slot where the expansion is placed, i.e.:
Slot 1 – XC11
Digital inputs: start at DI101
Digital outputs: start at DO101
Analog inputs: start at AI101
Analog outputs: start at AO101
Slot 2 – XC12
Digital inputs: start at DI201
Digital outputs: start at DO201
Analog inputs: start at AI201
Analog outputs: start at AO201
The following modules are available:
IOA-01: 1 analog input of 14 bits in voltage and current; 2 digital inputs; 2 analog outputs
of 14 bits in voltage and current; 2 open collector digital outputs. The analog input can be
in voltage (0 to 10 V / -10 to 10 V) or in current (0 to 20 mA / 4 to 20 mA).
The value read in AI101, for example, will be between-32768 and 32767. Further information
can be found in the expansion installation guide.
IOB-01: 2 analog inputs insulated in voltage and current; 2 digital inputs; 2 analog outputs
insulated in voltage and current; 2 open collector digital outputs. One of the analog inputs
is 0 to 10 V and the other -10 to 10 V when configured for voltage. If configured for current,
they can be 0 to 20 mA or 4 to 20 mA. The value read in AI101, for example, will be -32768
and 32767 for the configuration -10 to 10 V or 0 to 32767 for the other configurations.
Further information can be found in the expansion installation guide.
IOC-01: 8 Digital inputs; opto-coupled; 24 Vdc; configurable, high/low level actuation; 4
digital outputs; NO-contacts relay; capacity 240 Vac/1 A.
IOC-02: 8 Digital inputs; opto-coupled; 24 Vdc; configurable, high/low level actuation; 8
digital outputs; open collector; 24 V/0.1 A.
IOC-03: 8 digital inputs; optocoupled; 24 Vdc; configurable, high/low level actuation; 7 PNP,
protected outputs; 24 Vdc; 500 mA.
IOE-01: 5 inputs of single or triple PTC thermistors, with reinforced insulation compared
to the 0 V of the PLC300.
