9050JCK16V20 - Square D Time Delay Relay

9050JCK16V20 - Square D Time Delay Relay

The Square D / Schneider Electric 9050JCK16V20 on-delay timer is designed for control systems that need simple, dependable timing control. It’s commonly used in industrial panels, HVAC equipment, motor controls, conveyors, and other applications where a delayed switching function is required. With an adjustable timing range from 0.1 to 10 minutes, this timer gives technicians an easy way to fine-tune system operation without complicated programming or setup.

Once power is applied, the timer starts counting down. After the selected delay period, the relay contacts change state. When power is removed, the contacts return to their normal position. The adjustment knob on the top of the timer makes timing changes quick during installation, troubleshooting, or routine maintenance.

The 9050JCK16V20 uses a plug-in design that works with 8501NR51 and 8501NR52 relay sockets, helping simplify replacement in existing systems. It can be mounted on a 35 mm DIN rail or directly to a panel depending on the application. Its compact size is helpful in control cabinets where space is limited, while the DPDT contact configuration and 10-amp rating support a wide range of industrial control tasks. Built for long-term service, this timer continues to be a dependable option for maintaining existing equipment and control systems.
