Status output (Promag 50):
Open collector, max. 30 V DC / 250 mA, galvanically isolated
Configurable for: error messages, Empty Pipe Detection (EPD), flow direction, limit
values
Relay output (Promag 53):
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 contacts
Switch points for low flow cutoff are selectable
All circuits for inputs, outputs, and power supply are galvanically isolated from each
other.
