Signal on alarm
Current output
Failsafe mode selectable (e.g. in accordance with NAMUR Recommendation NE 43)
Pulse/frequency output
Failsafe mode selectable
Status output (Promass 80)
Nonconductive in the event of a fault or if the power supply fails
Relay output (Promass 83)
Dead in the event of a fault or if the power supply fails
Load
See "Output signal"
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.
Switching output
Status output (Promass 80)
• Open collector
• Max. 30 V DC, 250 mA
• Galvanically isolated
• Configurable for: error messages, Empty Pipe Detection (EPD), flow direction, limit values
Relay output (Promass 83)
• Max. 30 V, 0.5 A AC; 60 V, 0.1 A DC
• Galvanically isolated
• Normally closed (NC or break) or normally open (NO or make) contacts available
(factory setting: relay 1 = NO, relay 2 = NC)
