SchleicherUSA safety relays for reliable performance in various applications to protect people, equipment and systems.
Schleicher safety relays meet DIN ISO 13849 and DIN EN…
Even Safe Design doesn’t eliminate all hazards, so technical safeguarding is needed. The goal of the Safety Chain is to prevent persons from coming into contact with hazards, or to reduce hazards to a safe state before a person can come into contact with them.
Typical Hazards include shearing, cutting, catching, crushing and other impact injuries, as well as electrocution, burns, and exposure to dangerous substances.
Risk Assessment sensors in industrial applications monitor machine limits such as Speed, Load and Temperature. Performance outside of proscribed settings or limits activates the Safety Chain.
The Safety Chain consists of Input>Logic>Output components, in other words, Safeguard > Safety Relay > Contactor, to cut power or safely power down in a response to a given activity, malfunction or change.
Safety Sensors, Actuators or Switches are active or passive and include Emergency Stop Switch, Two-hand Control Station, Conditional enabling switch, Contact Fence or Gate, Light Curtain (senses break by hand or clothing), Step-on Safety Mat (detects entry to hazardous area), as well as Magnetic switch, Solenoid interlock and Holdup detection.
Signals from safeguarding components (sensors) are typically monitored by safety relays or safety PLCs (programmable logic control).
Various relay functions are required for various types of faults.
