• Digital Outputs: There are 4 digital outputs. Each output can drive a load with a maximum current of 1A, suitable for controlling small - to - medium - sized relays, solenoid valves, or indicator lights.
• Analog Inputs: There are 2 analog inputs. They can receive signals in the ranges of 0 - 10V or 4 - 20mA, with a 12 - bit resolution for measuring physical quantities like temperature, pressure, and flow.
• Analog Outputs: 1 analog output is available, capable of outputting signals in the same ranges as the analog inputs for precise analog control.
• Communication Interface: It supports an RS - 485 communication interface with Modbus RTU protocol, enabling seamless data exchange with other Modbus - compatible devices in an industrial network.

2. Applications

• Industrial Automation: In manufacturing plants, the RMP200 - 8 can be used to control and monitor simple to moderately complex production processes. For example, it can manage the operation of a single machine or a small section of a production line, such as controlling the speed of a conveyor belt or the opening and closing of a valve.
• Building Automation: In commercial or residential buildings, it can be applied to control basic building systems. For instance, it can control the lighting in a small area or adjust the temperature in a single room based on the input from temperature sensors.
• Small - scale Process Monitoring: In small - scale industrial processes, such as a local water treatment unit or a small - scale power generator, it can monitor process parameters like water level, pressure, and temperature, and take appropriate control actions.

3. Weight and Dimensions

• Weight: The unit weighs approximately 0.3 kg, which is relatively light and easy to install and handle.
• Dimensions: The overall dimensions are: length - 110mm, width - 80mm, height - 20mm. Its compact size allows for installation in limited spaces, such as in small control cabinets or on equipment panels.

4. Features

• Cost - effective Solution: With its relatively simple yet functional I/O configuration, the RMP200 - 8 provides a cost - effective option for applications that do not require a large number of I/O points.
• Modbus Compatibility: The support for Modbus RTU on the RS - 485 interface simplifies the integration of the device into existing industrial networks. It can communicate effectively with other devices such as PLCs, HMIs, and sensors, enabling coordinated control.
• User - friendly Setup: It has an intuitive configuration process, which can be easily understood and implemented by technicians and operators. This reduces the time and effort required for system commissioning.

5. Stability and Reliability

• Robust Design: The device is housed in a durable plastic enclosure that provides protection against dust, moisture, and minor mechanical vibrations. This ensures stable operation in normal industrial and building environments.
• Electrical Protection: It is equipped with basic electrical protection features such as over - current protection, short - circuit protection, and over - voltage protection for the inputs and outputs. These mechanisms safeguard the device from electrical faults and extend its service life.
• Quality Assurance: Through strict quality control during manufacturing and the use of high - quality components, the RMP200 - 8 offers reliable long - term operation.

6. Real - world Examples

• Small - scale Food Processing Plant: In a small - scale food processing plant, the RMP200 - 8 controls the operation of a filling machine. It receives signals from sensors to monitor the level of the filling material and controls the opening and closing of the filling valve via digital outputs, ensuring accurate filling of food products.
• Residential Heating System: In a residential building, it controls the heating system in a single room. It reads the room temperature from an analog temperature sensor and adjusts the operation of a small heater through the analog output, maintaining a comfortable indoor temperature.
