4. Structure and Composition

• Enclosure: Metal frame with IP20 protection (optional enclosure upgrade to IP54).
• Power Module: Accepts 24 V/48 V DC input, with internal rectification and voltage stabilization, and dual-channel redundancy.
• I/O Card: Configurable analog output card equipped with a 12-bit DAC (Digital-to-Analog Converter).
• Communication Board: Features Ethernet/serial port/fieldbus interfaces.
• Heat Sink: Adopts passive heat dissipation design to ensure thermal balance during long-term operation.
• Mounting Bracket: Compatible with DIN rail or 19″ rack, equipped with positioning buckles.

5. Typical Application Fields

• Power Industry: Monitoring of valves and transformers in power plants and substations.
• Petrochemical Industry: Flow meters, pressure sensors, and temperature control.
• Metallurgical Industry: Furnace temperature monitoring, cooling water flow monitoring, and liquid level monitoring.
• Water Treatment Industry: Monitoring of pump stations, valves, and PH sensors.
• Pharmaceutical Industry: Precision control of process variables (temperature, pressure).
• Automated Production Lines: Speed/position feedback for robots, conveyors, and servo drives.

6. Installation and Maintenance Points

Pre-Installation Inspection

1. Confirm that the power supply voltage (24 V DC or 48 V DC) is compatible with the module.
2. Check whether the fixing screws and positioning buckles of the cabinet or rail are in good condition.

Mechanical Installation

1. Slide the module into the DIN rail or 19″ rack, and ensure that the buckles are tightly engaged.
2. If upgrading the enclosure to IP54, install the protective enclosure first before fixing the module.

Electrical Wiring

1. Connect the power supply, signal lines, and communication lines according to the wiring diagram.
2. For analog outputs, use shielded wires and maintain consistent grounding to reduce noise.
