Carlo Gavazzi Automation

Safety modules

Carlo Gavazzi's safety modules, in accordance with the standards ISO 13849-1 and IEC 61508, are used in many different types of industrial machinery and sectors such as plastics, food and beverage, packaging, lifts and escalators, automotive and mining, wherever the machinery could pose a risk to people. Multiple inputs are available: e-stop, light curtains, e-gate, limit switch, interlock, magnetic sensor, mat, single beam sensor, two hands and speed control.

The following should be considered:
The EC machinery directive stipulates that machinery should not pose a danger (risk assessment in accordance with EN ISO 12100). The aim is to achieve an acceptable residual risk. If safety is dependent on control systems, these must be designed so that the probability of functional faults is sufficiently low. To meet this requirement, it makes sense to use harmonized standards like EN ISO 13849-1 to reach the best Performance Level (PLr): “Safety-related parts of control systems – Part 1: General principles for design”.
This standard may be applied to SRP/CS (safety-related parts of control systems) and all types of machinery, regardless of the type of technology and energy used (electrical, hydraulic, pneumatic, mechanical, etc.).
EN ISO 13849-1 also lists special requirements for SRP/CS with programmable electronic systems.
