- Weight: 0.15 kg, featuring a lightweight design for easy integration.
- Enclosure: Industrial-grade black or gray housing with IP20 protection.
Working Principle:
Receives data via the Modbus RTU protocol, processes the commands through its internal logic, and switches the corresponding output relays or analog circuits to actuate field devices.
Installation Requirements:
- Ensure adequate ventilation around the module to dissipate heat.
- Connect using shielded communication cables to maintain signal integrity.
Usage Precautions:
- Some versions support redundant configurations; verify wiring for dual power or communication interfaces if applicable.
- Do not exceed the specified voltage and current limits for connected field devices.
