Product Description
AO3082 is a Tricon series TMR triple redundant 8-channel analog output module, which is used in conjunction with the corresponding I/O base. It belongs to the SIS safety instrumented system card. It receives control instructions from the controller and outputs standard industrial analog control signals to drive safety equipment such as regulating valves and actuators, meeting the requirements of highly reliable safety control loops. It has SIL3 functional safety level certification.

IP20 (installed in the control cabinet)
Built-in Functions: Real-time self-diagnosis of channel short circuit / open circuit, fault transmission Product performance
Triple independent signal path hardware voting, a single path failure does not cause output failure, reducing the risk of false operation;
Each channel is independent, a single channel failure is isolated, and it does not affect the normal output of the remaining channels;
Continuous loop diagnosis, timely identification of line breakage and short circuit abnormalities;
Hot-swappable design, faulty card components can be replaced online, the device does not require full-line shutdown;
Anti-electromagnetic interference design, suitable for complex industrial sites such as petrochemical and power. Application fields
Petroleum refining, natural gas processing, coal chemical industry, power plant ESD emergency shutdown system, F&G fire gas control system; compressor, heating furnace, reactor safety control loop, regulating valve, pneumatic actuator analog quantity regulation drive.
Model of the same series analog output card
AO3082: 8-channel analog output (Tricon)
AO3481: 4-channel analog output module
AO2481: 8-channel analog output base module for Trident system, compatible with Trident platform AO cards
Important distinction: AO3082 belongs to the Tricon system and cannot be directly replaced with the AO card of the Trident platform; the base model is not interchangeable.
