Introduction to Safety Relays

Dadisick safety relays
Safety relays are vital components in industrial automation, designed to protect both machinery and personnel by monitoring safety functions and controlling outputs. These specialized devices are engineered to stop operations safely in hazardous situations, ensuring compliance with stringent safety standards.
At Dadisick, we specialize in providing high-quality safety relays that meet the diverse needs of modern industries, enhancing workplace safety with reliable and innovative solutions.

What is a Safety Relay?

A safety relay is a device that executes safety functions, halting machinery or systems in a controlled manner when a risk is detected. It acts as a bridge between two circuits, allowing for precise control and monitoring of safety functions, continuously monitoring the connections and inputs from safety devices such as emergency stop buttons, safety light curtains, and safety interlock switches.. Safety relays are designed to be fail-safe, ensuring that even in the event of a component failure, the safety function remains operational. When a fault or unsafe condition is detected, the safety relay activates the necessary outputs to bring the machine to a safe state. This may involve disconnecting input and output circuit contacts or shutting down the machine. Equipped with features like dual-channel redundancy and fail-safe designs, safety relays are essential for monitoring devices such as emergency stop buttons, safety gates, and light curtains.
Dadisick's safety relays are built with advanced fault detection and forcibly guided contacts, ensuring maximum reliability in critical applications.

Core Features of Safety Relays

● Monitoring: Continuously checking the connections and inputs from safety devices.
● Dual-Channel Redundancy: Ensures continued operation even if one channel fails.
● Fault Detection: Identifies issues like short circuits, triggering appropriate responses.
● Fail-Safe Design: Defaults to a safe state during power or component failure.
● Forcibly Guided Contacts: Mechanically linked contacts prevent conflicting states.
● Activation: Triggering the necessary outputs to bring the machine to a safe state.
● Autonomous Disconnection: Disconnecting circuit contacts if issues like fusing or obstruction occur.
● Cycle Check: Automatically verifying the precise opening and closing of its contacts during each on-off cycle.
Dadisick integrates these features into our safety relays, offering robust solutions trusted by industries worldwide.

Safety Relay Applications in Industry

Safety relay applications span various sectors, ensuring compliance and protecting workers. Below are key uses:
Safety Relay for Emergency Stop Button

1. Emergency Stop Systems

Safety relays instantly shut down machinery when an emergency stop button is activated, and ensuring that the machine comes to a complete stop when activated to preventing accidents. Dadisick’s relays provide rapid, dependable responses for such critical scenarios.
Monitoring safety doors and gates, safety relays halt operations if access is detected during runtime, ideal for robotic cells and production lines. Safety relays ensure that the machine cannot be operated unless the guards are properly closed and secured.

3. Light Curtain Protection

Safety light curtains are used to detect the presence of objects or personnel in hazardous areas. Paired with light curtains, safety relays stop machines when personnel enter hazardous zones. Dadisick's safety relays integrate seamlessly with light curtains for enhanced safety, and monitor the signals from these light curtains and trigger appropriate actions, such as stopping the machine, to ensure the safety of workers.

4. Two-Hand Control Systems

Used in presses, these systems require both hands to start a cycle, both hands of the operator are required to be free of the hazardous area to reducing risks. Dadisick’s solutions ensure operator safety with precision.

5. Conveyor Systems

Safety relays monitor pull cords and other devices on conveyors, stopping them instantly in emergencies.

6. Elevator and Escalator Control

Ensuring safe operation, safety relays are critical in elevator and escalator systems, a field where Dadisick excels with tailored solutions.
Safety mats and edges are used to detect the presence of personnel or objects in dangerous areas. Safety relays monitor these devices and initiate appropriate safety actions when a potential hazard is detected.

How Safety Relays Work

● Signal Reception: Inputs from safety devices are received.
● Logic Decision: Internal logic assesses the need for action.
● Output Control: Controls devices like contactors to execute safety measures.
● Action Execution: Stops machinery or triggers alarms.
● Fault Protection: Enters a safe state if faults are detected.
Dadisick’s safety relays streamline this process, delivering consistent performance and peace of mind.
