Product Description

The 2ME904.90-1 is a sophisticated and reliable module designed for advanced industrial automation systems, featuring high safety and performance standards. To ensure optimal functionality, it requires Automation Studio version 4.2.5 or higher, Automation Runtime V3.08 or higher, SafeDESIGNER 4.2.0 or higher, and Safety Release 1.10 or higher.

This module includes status indicators for operating state and module status, allowing for easy monitoring. Diagnostic capabilities are robust, with both module run/error status provided through status LEDs and software, ensuring quick and accurate fault detection. The 2ME904.90-1 has a maximum internal cycle time of 1600 us and an internal I/O power consumption of 1.78 W, showcasing its efficiency and speed. Electrical isolation is a key feature, with isolation between channels and the bus, though not between individual channels. This enhances safety and reliability in operation. The module is CE certified, adhering to stringent safety and quality standards.

In terms of safety characteristics, the 2ME904.90-1 meets EN ISO 13849-1:2008 standards, achieving CAT 3 when using individual input channels and CAT 4 when using input channel pairs (e.g., SIL1 & SIL2) or more than two input channels. It is rated for Performance Level (PL) e, with a Diagnostic Coverage (DC) of over 94%, and a Mean Time to Dangerous Failure (MTTF_d) of 2500 years. Its mission time is a maximum of 20 years, providing long-term reliability. The module also complies with EN IEC 61508:2010, EN IEC 61511:2004, and EN IEC 62061:2010 standards, achieving a Safety Integrity Level (SIL) CL 3 and a Safe Failure Fraction (SFF) of over 90%. The Probability of Failure per Hour (PFH) for the module is less than 1*10^-10, and for openSAFETY wireless, it is less than 1*10^-14 multiplied by the number of openSAFETY packets per hour. The Probability of Failure on Demand (PFD) is less than 2*10^-5, with a proof test interval of 20 years, ensuring minimal failure risk. The 2ME904.90-1 features safe digital inputs with a nominal voltage of 3.3 VDC and an error detection time of 100 ms. The isolation voltage between channel and bus is 500 V_eff, providing robust protection. The maximum cable length for the module is 50 cm. In summary, the 2ME904.90-1 is a high-performance module offering extensive safety features, reliable diagnostics, and efficient operation, making it a vital component for advanced industrial automation systems.
