1. Intelligent HART communication integration
This is the core function of AI815. It supports HART protocol penetration communication, allowing the control system to collect 4-20 mA analog signals while reading digital information from on-site intelligent instruments such as pressure and flow transmitters.
2. Flexible signal processing
The module provides 8 single ended input channels and is compatible with industrial standard analog signals
3. High precision and fast response
12 bit resolution: ensures the delicacy of signal conversion and meets the accuracy requirements of most process industries.
10ms update cycle: extremely high sampling frequency, suitable for closed-loop control loops with high real-time requirements.
Low error: At 25 ° C, the maximum error is only 0.1% of the range.
4. Industrial grade reliability and maintainability
Hot Swap: With the S800 I/O dock, modules can be replaced without turning off the system power, greatly reducing downtime for maintenance.
Electrical isolation: 8 channels are isolated from the system power and ground potential as a group (rated at 50V), effectively suppressing common mode interference.
Self diagnostic function: The panel is equipped with Fault and Run indicator lights, which can monitor internal hardware errors, undervoltage or overvoltage status in real time.
Each channel of this module has an overvoltage and undervoltage tolerance of up to ± 11 V d.c., effectively preventing damage to the core circuit caused by abnormal surges in field instruments. The internally integrated current limiting function can provide safe power supply for on-site two-wire transmitters, and can automatically limit current output even in the event of external short circuits.
In addition, the module adopts inter group electrical isolation design (rated isolation voltage of 50 V), completely separating the 8 input channels from the system backplane and ground potential. Combined with high-precision (12 bit) digital filtering technology, it can significantly suppress common mode interference and prevent ground circuit current backflow. Combined with hot swap function, it achieves dual safety protection at the physical layer and system layer.
