Relay Output Contacts
Each relay output R1, R2, R3 and R4 has
galvanic isolation between coil and contacts
to intrinsically safe standards, so different
external intrinsically safe control circuits may
be connected to the Sentro 8 Sensorstation.
Datacomms Ports
Datacomms signals must be approved
intrinsically safe. The power supply for the
datacomms signal may come from a different
intrinsically safe source.
