Industrial Applications

1. Automatic Conveyor Sorting Systems

Perfectly utilizes the 24 digital DC inputs to handle photoelectric proximity sensors and encoders, combined with 16 relay outputs to actuate pneumatic diverters and motor starters. The 8K program memory supports complex sorting logic.

Problem Solved

Solves the challenge of sorting varied-size packages on high-speed conveyor belts under changing power grid conditions thanks to its robust 100-240 VAC input tolerance and rapid cyclic scan execution.

2. Horizontal Flow Wrap Packaging Machines

Leverages the built-in high-speed counter functionality and RS-232C interface to sync with rotary encoders and HMIs. It drives 24VDC inputs from registration mark sensors and triggers relay outputs for sealing jaws and cutters.

Problem Solved

Eliminates synchronization errors between film feeding and cutting by executing fast immediate refreshing of input/output states within a compact, space-saving panel footprint.

3. Multi-Pump Pressure Control Systems

Manages pump sequencing, run-time equalization, and fault detection using its 24 inputs (for level switches, pressure switches, and thermal overloads) and 16 relay outputs (for contactors and valve actuators).

Problem Solved

Avoids pump wear imbalances and prevents water hammer by sequencing multiple heavy-duty pumps precisely, even when mounted inside narrow wall-mount outdoor panels due to its slim 79 mm depth.
