Signal on alarm • Current output → failure response selectable (e.g. in accordance with NAMUR recommendation NE 43)
• Pulse/frequency output → failure response selectable
• Status output (Promag 50) → non-conductive by fault or power supply failure
• Relay output (Promag 53) → de-energized by fault or power supply failure
Load see "Output signal"
Low flow cutoff Switch points for low flow cutoff are selectable.
Galvanic isolation All circuits for inputs, outputs and power supply are galvanically isolated from each other.
Switching output Status output (Promag 50, Promag 53)
Open collector, max. 30 V DC / 250 mA, galvanically isolated.
Configurable for: error messages, Empty Pipe Detection (EPD), flow direction, limit values.
Relay outputs (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.
