What is the purpose of the signal contact on the safety valve MS6-SV?
The signal contact on the safety valve MS6-SV is designed to signal whether the valve is ready to be switched on, i.e. the valve runs a self-test after switching on. If everything is in order, the signal contact switches to the high state. The valve with two enable inputs can now be switched on. The signal contact can be connected into the feedback loop of a safety control system.
