7.12 Inputs/outputs
This chapter describes input and output signals such as
digital inputs, relay outputs, analog outputs, temperature
inputs, and extension IO (option).

7.12.1 Digital inputs
7.12.2 Relay outputs
7.12.3 Analog outputs
7.12.4 Temperature sensor
Internal IO
Internal IO are the integrated signals to the softstarter.
The internal IO provides the following:
• 5 Digital inputs
• 3 Relay output
• 1 Analog output
Extension IO (Option)
The softstarter can be extended with more inputs and
outpus by using the Extension IO module. Extension IO
provides the following:
• 8 Digital input
• 4 Relay output
• 1 Analog output
To use an extension IO provides the same possibilities to
use all the softstarters functions as
internal IO.
Available Extension IO. TBD
For example, an Extension IO is useful when a sequence
start is required.
Connect the Extension IO
• Set parameter Com3 function (12.01) to Extention IO.
• Connect the DX111 or the DX122 1Ca and 1Cb to
Com3 terminals.
• Use parameter group 11 to program the function of
each DX111/DX122 input and output.
External digital inputs (Extention IO) is configured with
the following parameters:
