E23 2oo2 Modular Redundant Control Sytems is used for high availability & reliability applications Both solenoids are energised at the same time for increased redundancy measures. Compatiable with all hazardous area solenoids.

Actual product may differ from above image. Product details should be verified before purchase.

Pneumatrol Modular Redundant Control System (MRCS) is operated through a 1/4″ remote mount 3/2 pilot operated valve with redundant solenoid module assembly, able to provide high flow & low power capabilities
2oo2 Modular Redundant Control System is used for high availability & reliability applications
Both solenoids are energised at the same time, if signal is lost to one of the two solenoids the main control valve / actuator will remain in its operating position
Both solenoids must be de-energised in order to return the main control valve / actuator to its non-operating position
The redundant solenoids module can be fitted to any of Pneumatrol’s standard 3/2 or 5/2 solenoid spring control valves which utilise the CNOMO solenoid interface

FEATURES

External or internal pilot air connection
Dual solenoid / spring return function
Pilot exhaust dust cap fitted as standard
Interchangeable CNOMO interface
Full range of hazardous & safe area solenoids
ATEX, IECEx, GOST CU TR and NEPSI are all available
Body material available in aluminium (standard) & 316 stainless steel

23 2oo2 Modular Redundant Control System

Product Overview

The ROSS Pneumatrol E23 2oo2 Modular Redundant Control System is a high-availability pneumatic control solution based on the proven E23 valve platform.

Designed for critical valve automation applications, the system incorporates a modular redundant architecture that helps improve operational reliability and supports continuous process operation in demanding industrial environments.

Manufacturer: ROSS Pneumatrol
Product Type: Modular Redundant Control System
Valve Platform: E23 Series
Voting Architecture: 2oo2 (Two Out of Two)
Application: High Availability and Reliability Systems

Understanding 2oo2 Architecture

A Two Out of Two (2oo2) architecture requires both independent control channels to agree before a control action is initiated.

This type of configuration is commonly selected where:

High process availability is required
Operational continuity is critical
System redundancy improves reliability
Valve automation must remain dependable
Process interruptions must be minimised

The redundant arrangement helps enhance control integrity while supporting stable system operation.
