The TRICONEX 3481S2 Analog Output (AO) module is a component of the TRICONEX Safety Instrumented System (SIS) and is produced by TRICONEX. It is used in industrial scenarios that require reliability and precise control, providing analog signal output to ensure the operation of production processes.
Core Functional Features
Triple Modular Redundancy (TMR) Technology: Using TMR technology, the module has three independent processing channels internally. During operation, the three channels process data synchronously and verify the results through a voting mechanism. If one channel fails, the other two channels ensure that the module outputs correct signals, maintaining system operation and improving reliability and fault tolerance.
Analog Signal Output: It provides 4-20mA analog output signals with an output accuracy of ±0.25%. It is suitable for application scenarios that require precision in analog quantity control, ensuring that industrial processes run according to preset parameters.
Resolution and Response: It has a 12-bit resolution, converts input digital signals into output analog signals, and meets the control needs of industrial equipment. The response time is less than 1ms, which enables it to respond to control system commands and adjust output signals to ensure the control of industrial equipment.
Isolated Channel Design: Each output channel adopts an electrical isolation design to prevent signal interference between channels and the intrusion of external electrical noise. In industrial electromagnetic environments, it ensures the purity and accuracy of analog signal output, keeps the module working stably, and provides control signals for on-site equipment.
Diagnostic Function: The module integrates a diagnostic function to monitor its own operating status in real-time. When internal faults or signal abnormalities are detected, it can locate the fault point and feed back to operators through the system, facilitating fault 排查 and maintenance, reducing equipment downtime, and lowering maintenance costs.
Modular Design: It adopts a modular structure design, which facilitates disassembly, replacement, and expansion during system installation and maintenance. During the upgrading or transformation of industrial systems, the number of modules can be increased or decreased according to needs to adapt to industrial automation projects of different scales.
