Description
3.4 Mode of operation
The six digital outputs are individually isolated and act as normally open contacts, i.e. they
are either low resistance or high resistance. The maximum of four acoustic emission sensors
are connected to the four-pole "Sens1" to "Sens4" blocks. In each case, two terminals
provide the supply for the sensor electronics and two terminals are used to connect the
sensor signal.
Different standard signals can be connected at each of the four universal inputs "In 1" to
"In 4". The wiring of the four terminals must be adapted depending on the signal or sensor
type (0/4 to 20 mA, digital signal 24 V, normally open contact, NAMUR proximity sensor).
