Technical data Proline Promass 83 PROFIBUS DP/PA
150 Endress+Hauser
Relay output
De-energised by fault or power supply failure
PROFIBUS DP/PA
Status and error messages according to profibus Profile Version 3.0.
Load See “Output signal”
Relay output: Normally closed (NC or break) or normally open (NO or make) contacts available (default:
relay 1 = NO, relay 2 = NC), max. 30 V / 0.5 A AC; 60 V / 0.1 A DC, galvanically isolated.
Configurable for: error messages, Empty Pipe Detection (EPD), flow direction, limit values, batching
valve 1 and 2 (optional).
Low flow cut off Switch points for low flow cut off are selectable.
Galvanic isolation All circuits for inputs, outputs, and power supply are galvanically isolated from each other.
10.1.5 Power supply
Electrical connections → Page 26 ff.
Supply voltage 85...260 V AC, 45...65 Hz
20...55 V AC, 45...65 Hz
16...62 V DC
Cable entry Power supply and signal cables (inputs/outputs):
• Cable entry M20 x 1.5 (8...12 mm)
• Threads for cable entries, 1/2" NPT, G 1/2"
Connecting cable for remote version:
• Cable entry M20 x 1.5 (8...12 mm)
• Threads for cable entries, 1/2" NPT, G 1/2"
Cable specifications (remote
version)

Power consumption AC: <15 VA (including sensor)
DC: <15 W (including sensor)
Switch-on current
• max. 13.5 A (< 50 ms) at 24 V DC
• max. 3 A (< 5 ms) at 260 V AC
Power supply failure Lasting min. 1 power cycle:
• EEPROM or T-DAT saves measuring system data if power supply fails.
• S-DAT: exchangeable data storage chip which stores the data of the sensor (nominal diameter,
serial number, calibration factor, zero point, etc.)
Potential equalisation No measures necessary.
