Valmet D201134L (AI8C) 8-channel analog input module

Valmet D201134L (AI8C) 8-channel analog input module

D201134L (AI8C) is an 8-channel analog input module in the ACN I/O series of DNA DCS systems produced by Valmet. D201134L is responsible for collecting 4~20mA, 0~10V analog signals output by on-site transmitters, and also supports RTD thermistor and thermocouple temperature signals. It converts process parameters such as on-site pressure, liquid level, flow rate, and temperature into digital signals and uploads them to the ACN controller through the DNA backplane bus; D201134L is equipped with channel level fault diagnosis, supports HART signal reading, enables continuous monitoring of process parameters, and provides on-site measurement data for DCS system closed-loop regulation and process alarm.

Product features

1. 8-channel multifunctional analog acquisition, software configuration of multiple signal types including current, voltage, thermistor, and thermocouple, with strong module universality and reduced spare parts.
2. Supports HART protocol, can read intelligent HART transmitter device information, device diagnosis, and achieve remote management of instruments.
3. Channel level diagnosis can detect faults such as wire breakage, short circuit, and over range, and upload fault information to DCS for maintenance personnel to quickly locate measurement point faults.
4. Supports online hot plugging, allowing for module replacement without shutting down the system, without affecting the normal acquisition of other channels, ensuring the continuous operation of the device.
5. Wide temperature industrial grade design, capable of withstanding environments ranging from -20 ℃ to+70 ℃, and suitable for high-temperature conditions in on-site control cabinets.
6. High density compact modules reduce the space occupied by control cabinets and are suitable for large-scale centralized collection of measurement points.
7. Built in digital filtering to suppress on-site electrical noise and ensure stable measurement signals.
8. Native compatibility with Valmet DNA ACN rack, high-speed bus communication on the backplane, and high real-time data performance.
