61F-GPN-BT 24 VCC

Overview of Omron 61F-GPN-BT-24 VCC

The Omron 61F-GPN-BT is a conductive level controller powered by 24 VDC, designed to detect liquid levels without the need for a float. It utilizes an AC sine wave voltage between electrodes to prevent electrical corrosion, providing stable and reliable liquid level sensing. The unit supports automatic supply and drainage control and is suitable for environments without AC power supply due to its DC power capability.

Key Features of Omron 61F-GPN-BT-24 VCC

• Power Supply: 24 VDC (±15%) allowing use in locations without AC power.
• Output Types: Open collector (NPN) output with max 30 VDC, 100 mA, and relay contact output SPST-NO rated at 5 A, 240 VAC or 30 VDC.
• Detection Method: AC sine-wave voltage between electrodes prevents corrosion and prolongs electrode life.
• Sensitivity: Adjustable operation resistance from 0 to 100 kΩ for a wide variety of liquid types.
• Automatic Control: Switching between water supply and drainage modes using terminals 7 and 8 (open or shorted).
• Control Output: Outputs designed for direct PLC input or pump/valve control.
• Life Expectancy: Electrical life of 100,000 operations minimum; mechanical life of 20,000,000 operations minimum.
• Environmental Ratings: Operating temperature -10 to 55°C, humidity 25% to 85%, insulation resistance 100 MΩ minimum, dielectric strength 2000 VAC.
• Response Time: Operating time max 1.5 s; release time max 3.0 s.
• Size and Mounting: Compact dimensions (approx. 84 × 38 × 49.4 mm), DIN rail mounting with hold-down clip accessory.
• Certifications: UL61010-1, CAN/CSA C22.2 No.61010-1, EN61010-1, EN61326-1 compliant.
