Over 30 years of experience in the field, 4 generations of product iterations, and global deployment of over 10000 TMR systems.

Complies with IEC 61508 and meets mainstream SIL 2/3 safety requirements.

Flexible redundancy

Controller: Single/Dual/TMR optional.

IO network: Single/Dual/TMR optional.

IO module: Single/TMR optional.

Environmental tolerance: Class 1, Division 2, G3 compatible, suitable for harsh working conditions.

Efficient integration

Seamless integration with basic process control systems and standardized interfaces.

Software reusability and automated tools reduce deployment costs and human errors.

Network security enhancement

Lock application code, permission control, security logs, and strengthen protocols.

Achilles Level 1 certification to resist DOS and buffer overflow attacks.

3. Key functions and features

Characteristic Core Description

High availability redundant controllers, power supplies, and local area networks ensure the availability of security functions

HART compatibility supports intelligent field instruments, empowering operation and maintenance management

Channel configuration digital output supports excitation/de excitation, channel by channel configuration

1ms SOE full point event sequence recording, no dedicated hardware required

Universal IO single point configuration analog input/output, reducing spare parts and cabinet space

Advanced diagnostic full IO/network/controller diagnosis, no loss of alarm in case of disconnection

Rapid development supports FBD, causal matrix, ladder diagram, and quick reuse of library functions

Complete SIF full loop analysis and parameter calculation using the exSILentia tool for safety management

4. System composition

Controller: Core processor+redundant Ethernet, supports single/dual/TMR, real-time operating system execution logic.

IO module: directly connected to on-site equipment, without relay terminals; Single IO=1 component, TMR IO=3 components.

IO network: dedicated 100MB deterministic duplex protocol, supporting local/distributed IO.

Virtual controller: PC simulation, supporting program execution, communication, and alarm management.

5. Redundancy and SIL configuration (typical)

TMR 2oo3: SIL 3 (loss of excitation trip), SIL 2 (excitation trip).

Double 1oo2: SIL 3 (loss of excitation trip).

Single weight 1oo1: SIL 2 (loss of excitation trip).

6. Certification system

Safety standards: IEC 61508:2010, EN50402.

Product certification: UL/CE/CSA/EN 61010-1, Demko ATEX.

Cybersecurity: Achilles Level 1.

Quality system: ISO 9000.
