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.
