3. Product Features
- Multi-Range Configuration: Supports voltage or current input modes; input range can be configured as 0…5V, 0…10V, 4…20mA or 0…20mA.
- Anti-Interference Design: Adopts shielding design, with high impact resistance and vibration resistance, and extremely high MTBF (Mean Time Between Failures).
- Indicator Status: The module is usually equipped with indicators (about 18 pieces) for displaying communication status, error prompts and input channel status, facilitating on-site diagnosis.
- Hot Standby Function: Supports hot standby system to ensure stable operation of the system when the main module fails.
- Safety and Reliability: Complies with industrial automation standards, has electrical isolation function, and can effectively protect the control system from high-voltage impact.
