METSO IOP351 Relay Output Module

I. Overview

II. Technical Parameters

Power Supply Specifications: It adopts 24V DC power supply, which is widely used in industrial environments and compatible with most industrial power supply systems to ensure stable power supply for the module. Its maximum power consumption is only 12W, which meets the high-performance operation of the module while effectively reducing energy consumption, conforming to the industrial development trend of energy conservation and environmental protection.

Output Channels: It is equipped with 8 analog output channels and 12 digital output channels. The analog output supports 4-20mA current signals and 0-10V voltage signals, with an output accuracy of ±0.1%, which can accurately control the action of actuators. The digital output is a relay output with a contact capacity of 250V AC/30V DC, which can directly drive small motors, solenoid valves and other equipment.

III. Functional Features

Hybrid Signal Processing: It has both analog and digital input/output functions, capable of processing multiple signal types in industrial production simultaneously, without the need for additional modules. This simplifies the system architecture, reduces equipment costs and installation space. For example, in an automated production line, it can simultaneously collect analog parameters such as temperature and pressure, and digital signals such as equipment operating status, and output corresponding analog control signals and digital switch commands according to control requirements.

High Precision and High Stability: The high precision of analog input and output ensures the accuracy of signal measurement and control, reducing production quality problems caused by signal errors. The fast response and stable performance of digital input and output ensure the timely capture of equipment state changes and reliable action of actuators. The module uses industrial-grade components and advanced circuit design, with strong anti-electromagnetic interference ability, and can still work stably in complex industrial electromagnetic environments.

Flexible Configuration and Expansion: It supports flexible setting of parameters of input and output channels through dedicated configuration software, such as signal type, range, alarm threshold, etc., which can be personalized according to different application scenarios. At the same time, the module has expansion capability, and the number of input and output channels can be increased by adding expansion modules to meet the needs of expanding industrial production scale.

IV. Application Scenarios

Food Processing Industry: In food production lines, IOP351 can collect analog signals such as temperature and pressure of sterilizers, and digital signals such as the operating status of conveyors and the switch status of valves. After analysis by the control system, it outputs analog signals to control the opening of steam valves to adjust temperature and pressure, and outputs digital signals to control the start-stop of conveyors and the switch of valves, ensuring that the food processing process meets the process requirements and guaranteeing food quality and safety.

Building Materials Industry: In the cement production process, the module can collect analog parameters such as the feed amount and temperature of raw material mills, and digital signals such as equipment operating status, and transmit the data to the control system. According to the preset process parameters, the control system outputs corresponding analog signals through the module to control the speed of the feeder, adjust the feed amount, and outputs digital signals to control the start-stop of equipment, realizing automatic control of cement production, improving production efficiency and product quality.
