9050JCK16V20 - Square D Time Delay Relay

9050JCK16V20 - Square D Time Delay Relay

The Schneider Electric 9050JCK16V20 socket‑mounted on‑delay timer provides precise, fail‑safe sequencing for industrial control panels and automated systems. Part of the trusted Harmony 9050 JCK series, this plug‑in timer lets you set delay intervals between 0.1 and 10 minutes with a simple dial. Once power is applied, the countdown begins—and when time’s up, a dependable DPDT relay switches on. Remove voltage and the unit resets, making it ideal for machinery startups, lighting controls, pump sequencing, and HVAC automation.

Key Features and Benefits

• Customizable Delay Range: Easily adjust from 0.1 to 10 minutes—perfect for flexible timing needs.
• Dual Voltage Flexibility: Accepts 120 VAC or 110 VDC input, allowing use in diverse control environments.
• Reliable Switching Output: DPDT contact rated at 10 A resistive or ½ HP inductive at 120/240 VAC handles motors and lighting loads smoothly.
• Plug‑and‑Play Installation: Installs quickly into 8501NR51 or 8501NR52 sockets—great for retrofit or new panel builds.
• Extreme Temperature Tolerance: Rated from –28 °C to 66 °C (–18 °F to 150 °F), so it works in harsh factory or outdoor conditions.
• Regulated Quality: CE marked, UL Listed and Recognized, CSA certified for safety and performance you can trust.

Where It Works Best

• Appliance to control motor startups, conveyor belts, or pump operation in automation systems.
• Delay control for lighting and motor circuits in factories, warehouses, and process systems.
• HVAC sequencing—ensuring fans or compressors activate only after proper delay.
• OEM builds or controls panel upgrades needing modular, easy‑replace components with minimal wiring changes.
