AC 220V Time Delay Relay Module, Adjustable On Off Delay Timer, Waterproof for PLC

AC 220V Trigger Delay On-Off Timer Relay Module - Adjustable, Waterproof What this product does This AC 220V Trigger Delay Switch is a compact timer relay module designed to switch loads on or off after a configurable delay. The board accepts a trigger input and drives a relay output for reliable on-off control, making it suitable as a PLC accessory, relay box component, or a tester for control circuits. Key benefits - Precise timing control: Adjustable delay timing lets you set the activation or deactivation interval to match your application needs. - Simplifies automation: Use the module to add timed control to motors, pumps, lights, valves, and other AC devices without changing your main control system. - Space saving and easy integration: Compact board design fits into control panels or relay boxes and integrates with PLC systems and standard control wiring. - Durable for demanding environments: Sealed, waterproof construction helps protect the electronics from moisture and dust in workshops, outdoor enclosures, and industrial settings. - Reliable switching: Mechanical relay output provides clear open and closed contacts for switching AC 220V loads and for interfacing with other control equipment. Important attributes - Function: Trigger input activates an adjustable delay timer that switches the relay between on and off states. - Voltage compatibility: Designed for AC 220V control circuits. - Adjustable timing: User-adjustable delay setting for flexible timing intervals. - Interface: Standard relay contacts for safe integration with loads and PLC inputs. - Form factor: Compact board suitable for mounting inside relay boxes or control cabinets. - Durability: Sealed waterproof housing for protection in damp or dusty environments. - Application role: Can be used as a timer relay module, PLC accessory, relay box component, or testing module for control circuits. Practical use scenarios - Lighting control: Delay turn-off for exterior or stairwell lighting so lights remain on for a set time after a trigger event. - Motor and pump sequencing: Start or stop pumps and small motors with a timed delay to prevent mechanical shocks or to coordinate multi-stage systems. - Automation and testing: Integrate with PLCs or use as a standalone tester to validate control logic, timing sequences, or relay behavior in maintenance and commissioning tasks. What you get A ready-to-use AC 220V trigger delay switch board that functions as an on-off timer relay module, compatible with standard control wiring and designed for durable performance in relay boxes and control panels.
