Finder 72.51.0.024.0000 nestepinnan valvontarele, 400 V AC, 1 CO, DIN-kisko

Controlling liquid levels in tanks and reservoirs requires a reliable interface between conductive probes and pumps or valves. The Finder 72.51.0.024.0000 level control relay monitors conductive liquid levels and switches a changeover contact to manage filling or emptying operations.

Who is it for

This relay suits panel builders, maintenance technicians, and automation engineers who need a compact DIN-rail mounted level controller for industrial or commercial liquid handling systems.

Main features

• Supply voltage: 400 V AC, 50/60 Hz
• Single-level control (filling or emptying)
• 1 changeover (CO) output contact rated 10 A / 250 V AC
• Adjustable sensitivity range: 5 to 150 kΩ
• Low electrode voltage: 12 V AC for safe probe operation
• LED indicators for supply and relay status
• Mounts on 35 mm DIN rail, occupies 2 modules (35 mm width)

Specifications

• Contact material: AgNi (silver nickel)
• Power consumption: 3 VA
• Operating temperature range: -20 to +50 °C
• Dielectric strength (supply/contacts): 4 kV AC
• Dielectric strength (electrodes/contacts): 2 kV AC
• Max. switching power (AC1): 2500 VA

Tips

Use conductive probes with the appropriate sensitivity setting. Ensure the supply voltage matches the system and that the load does not exceed the contact rating.
