7.14 Inputs/outputs
This chapter gives a description of input and output
signals (I/O) such as digital inputs, relay outputs, analog
outputs, temperature inputs, and external digital inputs.
Chapter Function
7.12.1 Digital inputs
7.12.2 Relay outputs
7.12.3 Analog outputs
7.12.4 Temperature sensor
Internal I/O
Internal I/O are the integrated signals to the Softstarter.
The internal I/O provides these:
• 5 Digital inputs
• 3 Relay output
• 1 Analog output
Extension I/O (Option)
The Softstarter can be extended with more inputs and
outputs by using the I/O Extension module. The I/O
Extension module provides these:
• 8 Digital input
• 4 Relay output
• 1 Analog output
To use an extension I/O provides the same possibilities to
use all the Softstarters functions as for the programmable
internal I/O.
Available I/O Extensions. See chapter 5.1.3 Extension
I/O.
For example, an extension I/O is useful when a sequence
start is necesssary.
Connect the I/O Extension
• Set parameter Com3 function (12.01) to the I/O
Extension.
• 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 (extension I/O) have these
parameters:
Parameter
12.01 Com3 function
Description
Set the function of the Com3
port to Extension IO
1SFC132081M0201
Setting range
None, Test, modbus RTU slave,
Extension IO.
