- Grouped Multi-channel Output: Equipped with 16 independent digital output channels divided into two groups to realize grouped control, meeting synchronous control requirements of multiple devices and loops. It saves rack slot space, reduces system configuration costs and flexibly adapts to diversified on-site control demands.
High Load Capacity & Fast Response: Each channel provides up to 2A load current with a 12A total module rating, directly driving standard industrial devices such as contactors and solenoid valves without additional power amplification modules. The 1ms ultra-fast response ensures timely execution of control commands and avoids production delays caused by signal lag.
- Comprehensive Protection Mechanism: Built-in 8A group fuses effectively prevent module and equipment damage from overcurrent. 2500Vrms opto-isolation and 700Vrms inter-group isolation restrain signal interference and fault propagation. Reverse power connection protection further enhances operational safety and service life of the whole system.
Convenient Fault Diagnosis & Maintenance: Integrated LED indicators visually display individual output status and module faults for rapid fault location. Detachable terminal blocks simplify wiring and daily maintenance; hot-swap capability in partial applications minimizes downtime and maintenance costs.
- Superior Environmental Adaptability & Compatibility: The rugged industrial design ensures stable operation in wide temperature ranges from -40℃ to 85℃, high vibration and strong electromagnetic interference environments. With IP20 protection, it is suitable for harsh working conditions in metallurgy, chemical and other industries. It is fully compatible with Modicon Quantum systems, Unity Pro software and mainstream industrial protocols for seamless DCS and automation system integration.
- Energy-saving & Eco-friendly Design: Low basic power consumption of 1W reduces energy consumption. Compliant with REACH, RoHS and other environmental regulations, it meets green factory construction standards. Modular design optimizes spare part management and lowers inventory and resource waste.
