The Triconex 3805E is a high-performance analog output module. The following is its detailed description:
- Signal Conversion: Its main function is to convert digital signals into analog signals to drive actuators such as valves, motors, and pumps, realizing precise control of process variables.
- High Reliability: Adopts Triple Modular Redundancy (TMR) design, complies with Safety Integrity Level (SIL) 3 requirements, and ensures the system operates normally even in case of faults.
- High Precision: Output accuracy is as high as ±0.1%, suitable for industrial scenarios requiring high-precision control.
- Hot-Swap Function: Supports hot swapping, allowing maintenance and replacement of the module without shutting down the system, facilitating operation.
- Output Type: Current (4-20mA)
- Number of Channels: 8 points
- Resolution: 12 bits
- Output Accuracy: Less than 0.25% of Full Scale Range (0-21.2mA) within the 4-20mA range (at 0-60°C)
- Overrange Protection: Equipped with +42.5VDC continuous overvoltage protection function
- Response Time: ≤2ms
- Input Voltage: 24V DC
- Operating Temperature Range: 0-60℃
- Dimensions: 120mm x 80mm x 30mm
- Weight: Approximately 0.75kg
- The module monitors its own current output and maintains an internal voltage reference to provide self-calibration and module health information. Each channel is equipped with a current loopback circuit, which can verify the accuracy and existence of analog signals.
- Continuous diagnosis is performed on each channel and circuit of the module. Any diagnostic failure will deactivate the faulty channel, activate the fault indicator, and further activate the chassis alarm. Open-loop detection is provided by the LOAD indicator, which will be activated if the module fails to drive current to one or more outputs.
