2oo3 Modular Redundant Control System 2oo3 voting system for both the energising and de-energising signals The MRCS removes the need to rely on just one solenoid valve to open or close the process valve. Compatiable with all hazardous area solenoids.

  • Compact manifold designs
  • Interchangeable CNOMO interface coil units, including various hazardous area options
  • Solenoid Operator: SIL 2 on energising, SIL 3 on de energising
  • ATEX, IECEx, GOST CUTR and NEPSI coil certification
  • Individual pneumatic visual indication for each solenoid as well as for the input to and output from the whole system. This allows for visual verification that the whole assembly is working as required and full visual diagnostic of the manifold to identify which solenoid requires maintenance, should a fault ever occur.
  • Individual solenoid isolation. This allows any single solenoid to be isolated for service/replacement while the other solenoids can continue to operate normally, which means that the solenoids can be maintained without taking the whole manifold system out of service.

2OO3 & 3OO4 MRCS

Compact pneumatic solenoid valve manifold systems designed for use in applications where very high reliability and availability is required. These manifolds embed a “two out of three” (2oo3) or “three out of four” (3oo4) voting system for both the energising and de-energising signals. Manifold material available in Aluminium or 316 Stainless Steel
