Passerelle Modbus Sortie 4-20ma : Scénarios d'application typiques

Modbus Gateway is a protocol converter that enables communication between devices with different protocols. It is widely used in industrial automation systems to convert Modbus RTU/ASCII protocols to Modbus TCP/IP protocols. The 4-20 mA output is the standard for transmitting analog signals over long distances in many industries. This article discusses typical application scenarios for a Modbus gateway with 4-20 mA output.

Industrial Automation

In industrial automation, the Modbus Gateway with 4-20 mA output is commonly used to connect various sensors and actuators to a control system. The 4-20 mA output provides reliable data transmission over long distances, even in environments with high levels of electrical interference. Sensors such as temperature, pressure and flow can be connected to the control system via Modbus Gateway, enabling real-time monitoring and control of industrial processes.

Building Automation

Building automation systems typically use Modbus Gateway with 4-20 mA output for HVAC control, lighting control and energy management. For example, temperature sensors in different rooms can send data to a central control system via a Modbus gateway to enable efficient temperature control throughout the building. Similarly, energy consumption data from various devices can be collected and analyzed to save energy.

Water Treatment Station

In water treatment stations, a Modbus Gateway with 4-20 mA output can be used to monitor and control various processes. Sensors measuring parameters such as pH, turbidity and chlorine content can send data to the control system via the Modbus Gateway. This enables real-time monitoring and control of water quality, ensuring safe and efficient plant operation.

Oil And Gas Industry

In the oil and gas industry, the Modbus Gateway with 4-20 mA output can be used to remotely monitor and control oil and gas wells. Sensors measuring parameters such as pressure, temperature and flow rate can send data to the control center via the Modbus gateway. This enables real-time monitoring of well status and rapid response to any anomalies, thereby improving the safety and efficiency of oil and gas operations.Passerelle Modbus Sortie 4-20ma : Scénarios d'application typiques
