2.1 Modules
An Ex-proof module is a combination of an R/C panel, a transmitter supply unit and if needed, an isolating
repeater to drive a XB coil. To comply with the intrinsic safe requirements, the system power supply is located
in a separate 14 TE wide location.
2.2 Intrinsic safe electronic units
2.2.1 Transmitter supply unit for flow sensors
Power supply for intrinsic safe flow sensor, providing galvanic isolation between input, output and power
supply.
The unit is a one channel power supply and signal converter. 4(15) - 20 mA input; 4(15) - 20 mA output.
Power supply for the transmitter supply unit is 18 .. 35 Vdc (24 Vdc nominal)/63 mA.
