PROFIBUS PA interface
• Transmission technology (Physical Layer): IEC 61158-2 (MBP), galvanically isolated
• Profile version 3.0
• Current consumption: 11 mA
• Permissible supply voltage: 9 to 32 V
• Bus connection with integrated reverse polarity protection
• Error current FDE (Fault Disconnection Electronic): 0 mA
• Function blocks: 1 x analog input, 1 x totalizer
• Output data: volume flow, totalizer
• Input data: positive zero return (ON/OFF), totalizer control, value for local display
• Cyclic data transmission compatible with previous model “Promag 33”
• Bus address adjustable via miniature switches or local display (optional) at the measuring device

Switching output
Status output
• Galvanically isolated
• Max. 30 V DC/250 mA
• Open collector
• Can be configured for: error messages, empty pipe detection (EPD), flow direction, limit values
Low flow cut off
Low flow cut off, switch-on point can be selected as required
Galvanic isolation
All circuits for inputs, outputs and power supply are galvanically isolated from each other.
