Description Parameter
Digital inputs levels:
0 to 5.6 VDC logical level 0
7.2 to 40 VDC logical level 1
Note
Negative input voltage is not recognised.
Digital outputs parametres:
1 A Maximal continuous current
60 VDC, 42 VAC (Vrms) Maximal switching voltage
60 W Maximal switching capacity
• Digital I/O Management
To manage digital inputs and outputs via TCP software is required that handles the TCP connection.
For test purposes e.g. telnet can be used. The payload contains the states of the four inputs/outputs:
The value 0 represents the state “off”, the value 1 the state “on”.
0 7
OUT2 OUT1 IN2 IN1 0 0 0 0
○ Monitor the digital inputs and outputs
Every change of digital inputs triggers a message of the above format to be sent. It also contains
the valid states of the outputs.
○ Set digital outputs
To set the states of the digital I/O send the following pattern as ASCII characters
Description Pattern
Turn all digital outputs off 00000000
Turn output 2 on, turn output 1 off 00000001
Turn output 1 on, turn output 2 off 00000010
Turn output 1 on, turn output 2 on 00000011
○ Get status of digital inputs and output
To get the states of the digital I/O send the following pattern as ASCII characters
Description Pattern
Request a message with all states 00010000
