FOXBORO P0911QB-C  P0911QC-C Thermal resistance input/output module

FOXBORO P0911QB is A core module of Foxboro that is compatible with I/A series industrial control systems.

Its common specification is P0911QB-C. It is mostly used as a thermal resistor input/output or analog input module in industrial automation scenarios and is a key spare part for realizing signal processing and equipment linkage in industrial control.

The following is its specific information:

Core parameters

Power Supply and Signal

The working voltage often covers specifications such as 24VDC, and some configurations are compatible with a wide input voltage range of 100-240VAC.

The input frequency is compatible with the industrial general frequency band of 47-63Hz.

Under specific specifications, it can output 4-20mA analog signals, which can meet the signal matching requirements of most sensors and actuators in industrial scenarios.

Basic specifications

It adopts a modular structure design, weighs approximately 1.2KG, has an overall white appearance, and complies with the installation and layout standards within industrial control cabinets.

Some channels are marked with a program capacity of 6MB and a data capacity of 3MB, which can stably store basic control logic and collected data.

Core functions and features

The core function focuses on signal acquisition, processing and transmission in industrial sites.

It can be used as an input and output module for thermal resistors, as well as a ventilation module for bus input power supply.

It can be connected to sensors such as thermal resistors to convert physical quantities like temperature into electrical signals and transmit them to DCS or PLC systems, while simultaneously feeding back control instructions.

This module features high stability and flexibility.

Its modular design enables installation, maintenance and replacement without the need for an overall shutdown, allowing for quick component replacement to reduce production disruptions.

And it can be flexibly combined and adapted with the FOXBORO I/A series and GE General Electric series systems according to the control requirements of different industrial scenarios.

Typical application scenarios

Because it is compatible with DCS distributed control systems and PLC programmable control systems, it is widely used in industries such as petrochemicals, power, and metallurgy.

For instance, in the DCS monitoring system of a power plant, temperature signals of equipment such as steam turbines and boilers can be collected.

In the constant flow control system of chemical plants, it can be combined with sensors to achieve the transmission and control of flow-related signals.

It is also applicable to scenarios such as papermaking, dyeing and printing production lines, and integrated automation control systems of substations.
