Supply voltage Transmitter
• For device version with all communication types except Modbus RS485 intrinsically safe:
DC20 to 30 V
• For device version with Modbus RS485100 intrinsically safe: power supply via Safety
Barrier Promass 100
The power unit must be tested to ensure it meets safety requirements (e.g. PELV, SELV).
