Safety Relay – for emergency stop and safety gate monitoring, 24VAC/VDC, 2NO, DIN

Safety relay designed for safety circuits in industrial equipment, monitoring of emergency stop buttons, and safety gate/door limit switches. The relay features 2 N/O safety contacts, positively driven relay outputs, manual reset monitoring, LED indication, and is mounted on a DIN rail. It is a compact 22.5 mm wide safety control component for automation, manufacturing, and process control systems.

• Emergency stop circuits – for monitoring the status of E-STOP buttons and controlling safety outputs.
• Safety gate and door systems – for monitoring safety limit switches.
• Industrial equipment – in the safety circuits of machines, mechanisms, and production lines.
• Automation and process control systems – when a dedicated safety relay is required in the control circuit.
• Power control systems – when safety contacts are used to disconnect contactors, drives, or other control elements according to the schematic.

For example, the safety relay is installed in an automation cabinet on a DIN rail. An emergency stop button or safety gate limit switch is connected to the inputs, along with a manual reset button. The safety outputs are used to control contactors, drive control circuits, or other machine stopping elements according to the specific safety schematic.

When the E-STOP button is pressed or the safety gate is opened, the relay switches off the safety outputs. After the cause has been cleared, the system can be reset via the manual reset button, provided all safety conditions meet the design requirements.

The safety relay is a component of a machine safety circuit. It must be selected, connected, and tested according to the specific machine's risk assessment, safety function requirements, the manufacturer's manual, and applicable standards.

• Installation must be performed by a qualified automation or electrical professional with experience in machine safety circuits.
• Before starting work, disconnect power and verify that there is no voltage in the control and power circuits.
• Do not use as a generic universal relay – this is a device designed for safety circuits, which must be connected according to the safety schematic.
• Contact load must not exceed specified limits – 6 A, 240VAC, or 24VDC as per the provided specifications.
• Perform a functional test – the operation of the E-STOP, gate switch, reset, and safety outputs must be verified before commissioning.
• Do not bypass or bridge safety circuits – this can cause danger to human life and equipment.
