Typical application scenarios

Industrial production line control

Monitor the switch status of equipment such as robotic arms and conveyor belts(such as proximity sensors and limit switch signals).

energy management

Collecting relay contact status in the power system to achieve fault isolation and protection logic.

Environmental monitoring

Detect the switch signals of fire protection systems and security equipment(such as smoke detectors and access control status).

infrastructure

Monitor the start stop status of valves and pump units in water treatment plants to ensure process stability.

Technical advantages

High density design:32 input channels integrated into a compact module,saving cabinet space.

Flexible Expansion:Supports multi module cascading and adapts to large-scale control systems with 256 or more points.

Industrial grade reliability

Grouping isolation design reduces the risk of signal interference.
