ICS Triplex TC-215-02-4M5 Safety-level Analog Output Module
The ICS Triplex (now Rockwell Triconex) TMR triple-redundant safety instrumented system (SIS) is a highly reliable analog output card for high-risk industrial conditions. It focuses on fault tolerance and SIL safety certification, and is used to provide standard control signals for regulating valves and frequency conversion devices.

Core Hardware Parameters Table
Parameter Item Specification Details
Signal Output Format Standard 4-20mA, configurable 0-20mA current signal; supports 0-10V voltage output (activated platform configuration)
Control Precision Full-scale error ±0.1% to ±0.5%, equivalent resolution 12 to 16 bits
Architecture Characteristics TMR triple redundant voting design, single-channel device failure does not interrupt output
Safety Certification IEC61508 SIL3 safety level, TÜV authoritative certification
Power Supply Requirements 24VDC power supply on the system backplane, single card power consumption approximately 5W
Operating Temperature Range -40℃ to +70℃, suitable for chemical, oil and gas wide-temperature control cabinet environments
Protection and Diagnosis Channel short circuit, open circuit, over-temperature real-time self-check, faults actively reported to the main controller
Core Function Highlights
Deterministic Safety Output
Configurable continuous adjustment output, fault-safe fallback mode. When the system triggers interlock, it automatically outputs according to the preset value, driving valves to close, equipment to stop, suitable for safety interlock circuits.
Triple Redundancy Fault Tolerance
Three independent calculation voting internally, single-point component failure will not cause signal jump, circuit interruption, reducing the probability of accidental shutdown of high-risk devices.
Complete Loop Diagnosis
Continuous monitoring of external instrument loop connection, abnormal load, early warning of line aging, loose wiring, reducing on-site inspection blind areas.
Native System Adaptation
Plug-and-play connection to Triconex mainstream safety rack, and seamless networking with the same series of digital IO, communication modules, compatible with the entire SIS engineering software configuration.
Typical Application Scenarios
Petrochemical Refining: Reaction vessel feed control valve, cooling loop analog interlock control;
Oil and Gas Field Stations: Safety regulation of pipeline pressure/flow control valves, emergency throttling control;
Thermal Power Industry: Variable frequency speed regulation of boilers, safe regulation of wind door opening;
Existing Old System Spare Parts: Replacement and reuse of faulty cards of the same model in old Triconex racks.
