Foxboro PO911SM High-performance digital/analog input/output module

P0911SM is A high-performance digital/analog input/output module of the I/A series under FOXBORO. 

It is often used as a core control card in DCS systems and is suitable for various complex industrial scenarios with its stable signal processing capabilities. Here are the detailed information:

Core parameters and characteristics

The basic parameters are clear:

The working voltage is commonly marked as DC 24V and AC 220V (presumably different adaptation versions).

 The operating temperature range is -20 °C to + 70°C, the storage temperature range is -40 °C to + 85°C, and the humidity tolerance range is 5% to 95% (non-condensing).

 It can withstand most harsh industrial environments. The communication interface adopts RS-485. which can ensure stable signal transmission over long distances.

Strong anti-interference and reliability

Each channel of the module is completely isolated from the ground, which can effectively avoid signal interference between channels and ensure the accuracy of data collection. It is also equipped with a thermocouple burnout detection function, which can promptly identify abnormal signal transmission and further enhance the reliability of system operation.

Easy to maintain and operate

It adopts a compact structure design, which is suitable for the dense installation requirements of industrial control cabinets. And it can be disassembled and replaced without removing the wiring, power supply, etc. 

of the on-site equipment, with high maintenance efficiency. 

In addition, the red and green dual-color LED indicator lights on the front panel can visually display the operating status of the module, facilitating the staff to quickly troubleshoot.

Typical application scenarios

This module is compatible with the application scenarios of FOXBORO I/A series control systems and is widely used in multiple industries such as petrochemicals, power generation, cement, food and beverage, etc.

For instance, in chemical production, the temperature and pressure sensor signals of the reaction vessel can be connected to achieve precise collection and feedback of analog data, 

assisting the control system in adjusting process parameters. In thermal power plants, sensors that can cooperate with boilers, 

steam turbines and other equipment to complete signal processing and ensure the stability of the power generation process. In the production line of food processing plants, 

it can be connected to temperature control, pressure control and other equipment to ensure a stable and compliant production environment.
