Product Performance

Accurate protocol adaptability: Natively supports Limitorque protocol, can directly establish communication with Limitorque valve actuators without a protocol conversion middle layer, with command response delay < 10 ms. Efficient data transmission: Adopts asynchronous transmission mechanism to realize asynchronous operation between ControlLogix processor and devices, without occupying the core computing power of the controller; a single module can stably manage up to 32 compatible devices.

Strong system integration: Seamlessly compatible with Rockwell Automation ControlLogix system, supports RSLogix 5000 software configuration, provides ladder logic samples and Add-On Instructions (AOI), enabling rapid deployment without modifying existing control system programs. Excellent environmental adaptability: Wide-temperature design, enhanced anti-vibration and anti-shock structure, combined with electrical isolation technology, enables continuous operation in dusty, humid and electromagnetic interference environments, with Mean Time Between Failures (MTBF) ≥ 1.0×10⁶ hours.

Comprehensive diagnostic capability: Multi-status indicators feed back module operation, communication and fault status in real time; built-in error code storage function enables quick location of port faults or protocol anomalies.
