Emerson PACSystems RX3i CPS400 safety controller

Emerson has announced the PACSystems RX3i CPS400 safety controller, designed to enable Safety Integrity Level 2 (SIL2) strategies for infrastructure, fire and gas, burner management systems, and other emergency shutdown systems. The safety controller is a compact solution with robust security measures and a scalable architecture with 2000 available I/O points, suitable for complex projects with evolving requirements.

A 64 Mb memory capacity and scalable digital architecture enables the safety controller to support a diverse range of mission-critical applications. Using built-in industrial communications protocols, including OPC UA, Ethernet Global Data (EGD) and Modbus TCP, the controller is designed to connect peer-to-peer and with higher-level hosts.

As a secure-by-design solution incorporating Secure Boot and the Trusted Platform Module (TPM) standard, the controller is designed to provide data integrity and protection against potential threats. Safety-certified function blocks and pre-configured templates simplify overall system certification in accordance with the IEC 61511 standard.

Available in simplex or redundant controller configurations, the controller can perform all safety data messaging with duplex communications using the black channel principle over EGD, allowing standardised and reliable connectivity with Emerson’s PACSystems VersaMax SafetyNet I/O system. The platform is IEC 61508 safety-certified, providing a capable SIL2 simplified solution to help designers build appropriate protection schemes.

Developers can configure the new controller using familiar software tools employed for PLCs, operator interfaces and other automation elements.
