The PELC PT414S-8 is a conductive liquid level controller for 230VAC 50Hz mains. It detects the presence of a conductive liquid via three pendant electrodes (measuring electrode resistance 5–50kΩ) and controls a 10A/250VAC single-contact output relay. An 8-pin octal relay base (code 525086, sold separately) is required for installation.

Key Features

• Conductive liquid detection via 3 pendant electrodes (high, low, reference)
• Electrode resistance measurement range: 5–50kΩ
• Output relay: 1 contact, rated 10A / 250VAC
• Supply voltage: 230VAC 50Hz
• LED indicators for relay status
• Varistor surge protection on relay contacts
• Protection rating: IP41
• Housing dimensions: 42×89×92mm
• Mounts on 8-pin octal base (code 525086 — sold separately)

Product Benefits

• Automates pump control in water tanks, sump pits, and industrial reservoirs — no manual level checking
• Varistor protection on relay contacts extends contact life when switching inductive pump loads
• IP41 enclosure resists dust ingress in industrial panel environments
