sikkerhetsrelèmoduler

Sikkerhetsrelémoduler, sometimes referred to as safety relay modules, are crucial components in industrial automation systems designed to ensure the safety of personnel and equipment. Their primary function is to monitor safety-related functions and, in the event of a fault or hazardous condition, bring a machine or process to a safe state. This is typically achieved by safely disconnecting power to hazardous parts of the machinery.

These modules are designed to meet stringent safety standards, such as those defined by IEC 61508 or ISO 13849. They differ from standard relays in their internal construction and testing, which ensures a higher level of reliability and fault detection. Safety relay modules often incorporate redundancy and self-monitoring features. If an internal fault occurs within the module itself, it will trigger a safe state rather than failing in an unsafe manner.

Common applications for sikkerhetsrelémoduler include monitoring emergency stop buttons, safety light curtains, two-hand controls, and safety door interlocks. By integrating these safety devices with a safety relay module, manufacturers can create robust safety solutions that comply with regulatory requirements and significantly reduce the risk of accidents in industrial environments. The output contacts of a safety relay module are typically designed to be fail-safe, meaning they open reliably when power is removed or a fault is detected.
