The 8751-CA-NS Most secure network system is a new addition to the MTL Open System product family. Sharing the same basic platform products as process control, the new safety net controller, the new Earth Line Fault Detection (ELFD) controller carrier and two new Safety Net IO modules have been developed and certified. Safety net systems are supplied as process control products using the same field terminals, I/O module carriers, and power supplies. Perform configuration and application design using software tools, especially security applications – but in a common programming environment. Certified as a “Programmable Electronic Safety System” according to IEC 61508, the MOST Safety Net is intended for safety-related applications achieving Safety Integrity Level (SIL) 2. As PART OF THE OPEN SYSTEM COMPONENT FAMILY DESIGNED BY MTL FOR THE PROCESS AUTOMATION MARKET, IT CAN TIGHTLY INTEGRATE CONTROL SYSTEMS WITH MOST PROCESSES OR SYSTEM SOLUTIONS THAT WORK WITH ANY PROCESS CONTROL AS A STANDALONE SAFETY DEVICE.

8751-CA-NS The system will also be “publicly available” with the HMI of your choice – whatever package you use. Emergency shutdown, fire and gas, and burner management application requirements have been met before certification to IEC 61511 process industry and NFPA 85 burner management systems. The Safety Net system was designed for SIL 2, with features developed specifically for safety applications and designed to ensure safety, with simple and clear safety manual. The end result is a product that is easy to program, configure, and use. The modular approach provides a cost-effective I/O constrained security application solution with counts per node.

And because each safety net node can accommodate up to 64 I/O modules (8 channels per module), the security system requirements also meet high I/O counts. A single controller, input module, and output module (as well as the necessary field terminals, carriers, and power supplies, and appropriate sensors and end elements) meet all SIL 2 safety function requirements using the 1-in-1 diagnostic architecture (1oo1D). Redundant controllers can be used to improve the availability of SIL 2 safety features – completely bump-free transfers. Further enhancements to availability can be made through the use of redundant, fault-tolerant Ethernet communications and redundant power supplies.
