  1. MX 62

  2. MX 62 System SIL 3 Notified by EXAM N° BVS Pb 04/06X • Full redundant system (SIL 3) • Up to 64 digital or analog transmitters • Up to 128 addressable relays • Up to 64 programmable analog outputs • MX62 is not only a gas controller but a truly PLC dedicated to gas detection

  3. MX 62 System • The gas and flame control unit MX 62 enables: • to set up complex and elaborated installations. • to increase the availability of the system:SIL3 approved according to EN50402 • reduction of the material and wiring costs and of the whole equipment • to ensure supervisions .

  4. MX 62 Fonctionning safety of gas detection fixed systems

  7. MX 62 into detail • Power supplies • control module • Local or remote modules • LED modules • Display modules • Relay modules • Analog output modules • Softwares and interfaces • Housing.

  8. POWER SUPPLY BLOCK • The power supply block and its accessories (protections, switches, terminals) will be fixed in the housing • The power supply block will depend on the choice of the equipment: 13W maximum per channel 240 to 1500W

  9. Powers/protections/batteries: examples

  10. CONTROLLER MODULE(CPU):CM It is the control unit of the MX62. Two synchronised 16 bits micro-controllers run in parallel. They redundantly and permanently compare measurements and status of transmitters to initiate all necessary alarms. The u.c.enables the connection to PC/PLC, different modules and MMC uploading.

  11. No fault µC A inputs outputs µC B WARNING !!! The info received and exchanged between both processors are different µC A inputs outputs µC B Status of the controller :How does the MX 62 react in case of single fault. SIL 2 or SIL 3 applications System in normal operation. LOSS of one SIL LEVEL but the system is still safe .
