Actuators Providing SIL Capability for Auma Actuators
A new module designed by Auma provides enhanced Safety Integrity Level (SIL) capability for the company’s electric actuators. The development enhances the possible application of Auma’s modular actuation technology, which is widely adopted in safety-related systems, the company said.
The integral module, located within Auma’s AC actuator controls provides a simple and effective solution comprising transistors, resistors and capacitors. The AC actuator control advancement supports modern automation technology developments, including asset management, which require increasingly intelligent field devices with comprehensive software-based diagnostic functions. The new hardware-based integral SIL module improves the SIL capability of the devices: In standard operation mode the SIL module is inactive. If the safety related function is required, the module takes over actuator operation management.
