GAM900S - maximum safety
- SIL2-/PLd certified
- 2× MEMS capacitive, diverse redundant, 3-axis
- Max. 4 relay outputs, thereof 1 safe, internally redundant, SIL2/PLd compliant
- Customer-specific filter and relay configuration
Features
Safe detection by diverse redundant sensors
GAM900S incorporates two precise MEMS sensors to reliably detect shock and vibration as prevailing for example at wind turbines:
- Diverse redundant sensors to ensure systematic suitability and mandatory identification of common-cause failures.
- Components from different manufacturers are used, with different designs and different methods of signal processing.
Safe processing by certified software compliant to IEC 61508-3
From specification to validation, the GAM900S safety rated embedded software (SRESW) is compliant with the requirements of the safety standard IEC 61508-3:
- Extensive testings and detailed documentation of the safety-relevant software.
- Guaranteed independence of safety and standard software e.g. used for CANopen communication.
- Certified by TÜV Rheinland: Full compliance to safety integrity levels SIL2/PLd.
Safe monitoring by redundant relays
GAM900S utilizes two relays with readback contact:
- 2-channel addressing of relay and status cross-checked by the SRESW.
- Activation of the test input will identify any undetected error affecting the two relays, resulting for example from welded contacts.
- Depending on customer requirements, the relay contacts are either internally connected in series or available at two separate connectors.
