• Safety Certified: Complies with multiple international safety standards including CE, UL, and CSA, satisfying compliance requirements of global markets.
• Compact Size: Small footprint and lightweight design, suitable for installation in space-constrained control cabinets or enclosures.

4. Structure and Components

• Housing: Made of high-strength plastic or metal, providing mechanical protection with integrated screw holes for secure mounting.
• Terminal Block: Each output point is configured with an independent screw terminal, ensuring reliable and stable wiring connections.
• Internal Contacts: Silver alloy or copper alloy contacts are adopted to guarantee low contact resistance and extended service life.
• Internal Circuitry: Consists of driving transistors, protective diodes, and filter capacitors, forming a complete True-High output driving circuit.
• Markings: Each output point is clearly numbered from 1 to 16, facilitating easy mapping to corresponding points in PLC programming.

5. Typical Application Areas

• Industrial Automation: Driving indicator lights, alarms, and relays under PLC control.
• Process Control: Outputting start-stop signals for valve solenoids and pumping stations.
• Building Automation: Status indication for access control systems, fire alarm systems, and HVAC systems.
• Energy Systems: Condition monitoring and control of photovoltaic inverters and wind turbine generators.
• Packaging Machinery: Signal output for cylinders and sensors in packaging lines.

6. Installation and Maintenance Guidelines

Installation

1. Mount the module on guide rails or in enclosures compliant with IEC 60204-1 standards.
2. Securely fasten the terminal block to cables using screws to ensure excellent electrical contact.
3. Verify that the power supply provides a stable 24 V DC output to prevent malfunctions caused by voltage fluctuations.

Wiring

1. Connect the positive pole of each output directly to 24 V DC, and the negative pole (or common terminal) to the PLC’s output port.
2. For high-power loads, it is recommended to connect power relays or contactors in parallel at the output terminals to protect the module.

Commissioning

1. After power-on, use a multimeter to measure the voltage of each output point and confirm that it maintains 24 V DC in the de-energized state.
2. Test the corresponding points in the PLC program and verify that the output switches to low level (0 V) or remains at high level as instructed.
