METSO IOP321 Isolated Analog Output Module

• Precise Signal Output: It supports multiple standard analog signal outputs such as 4 - 20mA, 0 - 10V, and ±10V. According to the instructions of the control system, it can output stable signals with a high precision of ±0.1%, accurately driving actuators such as valves, frequency converters, and motors.​

• Electrical Isolation Protection: Using professional-grade isolation technology, each output channel has an electrical isolation capacity of up to 1500Vrms. It can effectively isolate electrical interference, surges, and ground loops between the output end and the control system, avoiding signal distortion and equipment damage, and enhancing system safety and stability.​

• Fault Diagnosis and Protection: The built-in intelligent diagnosis function continuously monitors faults such as abnormal output signals, disconnections, and out-of-range conditions. Once a problem is detected, it immediately triggers an alarm and activates the self-protection mechanism to ensure the safety and reliability of the output signals. Meanwhile, the working status and fault information of the channels are intuitively displayed through LED indicator lights, facilitating quick problem troubleshooting.​

• Flexible Configuration Management: It supports flexible configuration of parameters such as output signal types, range settings, and output modes through software or hardware DIP switches. This can meet the diverse control requirements in different industrial scenarios and be adapted to various control systems and actuators.​

• Output Channels: It has [X] independent analog output channels, supporting parallel output to control multiple actuators simultaneously.​

• Output Range: Current output: 4 - 20mA, 0 - 20mA; Voltage output: 0 - 10V, ±10V, etc.​

• Driving Capacity: The driving capacity of the current output channel can reach [X]mA, and the load capacity of the voltage output channel is [X]kΩ, ensuring stable driving of various loads.​

• Communication Interface: Equipped with various communication interfaces such as Profibus DP and Modbus RTU, it supports fast communication with control systems like PLCs and DCSs, enabling remote parameter setting and real-time monitoring.​

• Power Supply: 24V DC ±15%, with overvoltage, overcurrent, and reverse connection protection functions. It has low power consumption and stable operation.​

• Working Environment: The operating temperature range is -40°C - 70°C, and the storage temperature is -40°C - 85°C; the protection level is IP20, allowing stable operation in harsh industrial environments.​

• High Reliability and Stability: Industrial-grade high-quality components are selected and undergo strict aging tests and quality screening. The Mean Time Between Failures (MTBF) exceeds 200,000 hours, enabling long-term stable operation in complex industrial environments.​

• Convenient Installation and Maintenance: Adopting the standard 35mm DIN rail installation method, it has a compact structure, and installation and removal are simple and quick. It supports hot-swappable operation, allowing module replacement without system shutdown, reducing maintenance costs and downtime.​

• Strong Compatibility and Expandability: It can be seamlessly integrated into automation control systems of METSO and other mainstream brands. Multiple modules can be cascaded, making it easy to flexibly expand the number of output channels according to project requirements, meeting the needs of large-scale industrial control scenarios.​

• Process Control Field: In the production processes of industries such as petrochemicals, pharmaceuticals, and food and beverages, it precisely controls valve openings, regulates flow rates and pressures, ensuring stable and efficient production processes.​

• Power Systems: It is used for generator excitation control, transformer tap adjustment, power grid reactive power compensation, etc. in power systems, ensuring stable power supply and safe operation of the power grid.​

• Building Automation: In intelligent buildings, it controls the temperature adjustment of air conditioning systems, the brightness adjustment of lighting systems, the rotation speed of water supply and drainage pumps, etc., realizing intelligent management and energy-efficient operation of building equipment.​
