6.7 Signal Output S2
The status of the 2 output channels can be queried at signal output S2. This output
channel is short-circuit proof and has a common potential with the power supply
ground.
Use signal output S2 with a PLC!
Connect the supply ground of the electronic circuit breaker with the ground of the
PLC when you use signal output S2 with a PLC!
When a coded sampled signal is transmitted via control input S1, the circuit
breaker is synchronized automatically. The current status of the output channels is
then transmitted via signal output S2.
Observe the Number of the Output Channels!
The following tables and figures have been granted to:
• 787-1662: output channels 1 … 2 are valid
• 787-1664: output channels 1 … 4 are valid
• 787-1668: output channels 1 … 8 are valid
Invalid bits and bytes will not be analyzed. They will be transmitted in an
undefined state.
The table below provides an overview of the 17 data bits at signal output S2. A
distinction is drawn here between the status "on/off" and the error status
"tripped/overcurrent".
