Functional features

Signal Processing Capabilities

Analog Signal Processing: The module is capable of receiving and processing a wide range of analog input signals, such as those from temperature sensors (e.g., thermocouples, RTDs), pressure sensors, flow sensors, and so on. It can amplify, filter, linearize and other operations on these analog signals to improve signal quality and make them more suitable for subsequent processing and control. For example, for weak thermocouple signals, the module can amplify and convert them to standard voltage or current signal ranges, such as 0 - 10V or 4 - 20mA, and at the same time carry out linearization to ensure that the signals can accurately reflect the actual changes in physical quantities.

Digital signal processing: For digital input signals, such as those from limit switches, encoders, counters and other devices, the RL 01 module can perform logical operations, counting, frequency measurement and other operations. In automated production lines, it can count the digital pulse signals from product counting sensors to accurately count the number of products, or measure the frequency of signals from motor encoders to obtain information about the motor's speed.

Device Control Functions

Analog output control: The module is equipped with analog output channels, which can output 0 - 10V or 4 - 20mA control signals for driving various industrial actuators, such as regulating valves and frequency converters. Through these output signals, the actions of the actuators can be precisely controlled, thus realizing the fine regulation of industrial processes. For example, in chemical production, the opening of a control valve is controlled by outputting a 4 - 20mA signal, which in turn controls key parameters such as material flow or reaction temperature.

Digital output control: At the same time, it also has a digital output channel, capable of outputting high level or low level signals, which can be used to control the on/off of relays, contactors and other devices, thus realizing the start/stop control of motors, indicators and other devices. In a simple automation device, when specific conditions are met, the module can output a high level signal to make the relay close, and then start the motor to complete the corresponding production action.

Communication function

Communication protocol support: It supports a variety of industrial communication protocols, such as Profibus - DP, Modbus, CANopen and so on. This makes it easy to communicate with other devices, including programmable logic controllers (PLCs), host computers, human-machine interfaces (HMIs), and so on. For example, by communicating with PLC via Profibus - DP protocol, the module can transmit the collected field device data (such as sensor data) to PLC for centralized processing, and at the same time receive the control instructions sent by PLC, realizing the organic combination of distributed control and centralized management.

Data transmission function: During the communication process, the RL 01 module can effectively transmit all kinds of data, including equipment status data, control command data, process parameter data and so on. It can pack and check the data to ensure the accuracy and integrity of data transmission. For example, when transmitting equipment operating status data to the HMI, it will format and package the data in accordance with the requirements of the communication protocol and add a check code to prevent the data from making errors in the transmission process.

Technical Parameters

Electrical Parameters

Power supply voltage: Usually 24V DC is used for power supply, and it can work normally within a certain voltage fluctuation range (e.g. ±10% or ±20%). This stable power supply provides reliable power support for the internal circuits of the module, ensuring the normal operation of its signal processing, control output and communication functions in various industrial environments.

Power Consumption: The power consumption of the module is relatively low, generally within a few watts, depending on its operating status, such as the complexity of signal processing, the size of the load of the control outputs and the frequency of communication activities. Lower power consumption helps to reduce energy consumption and also reduces the risk of module failure due to heat generation.
