Equipment Matching Control: PLC control stations for large mechanical equipment, special equipment, and test equipment.

Small and Medium-sized Automation Projects: Automation control scenarios requiring 4 or fewer module combinations.

Six. Usage and Maintenance Installation

Choose an installation location that is ventilated, dry, and far away from strong electromagnetic interference.

Use DIN rail installation (recommended) or panel screws for fixation to ensure a secure installation.

Keep the back panel level and avoid tilting to prevent poor module contact.

Module installation

Install the power module first (recommended in the first slot on the left), then install the CPU module, I/O module, and communication module.

Align the module with the slot and push it in evenly. Once you hear the latch "click" sound, it is securely fixed.

Ensure good contact between the module and the back panel without any looseness.

Wiring

Connect the power module to a 24VDC power supply according to the specifications. Ensure the wiring is secure and avoid short circuits or reverse connections.

For the I/O module, connect the on-site signals and for the communication module, connect the network cable/fiber optic cable according to the corresponding module manual specifications. Maintenance

Regularly (every 3 months), check if the module clips are loose and if the connection terminals are securely fastened.

Keep the installation environment clean to avoid dust accumulation that affects heat dissipation and contact performance.

Avoid the back panel getting damp or getting water in, to prevent short-circuit faults.

When replacing the module, ensure that the new module model is the same as the original module. I/O modules that support hot swapping can be replaced online, while CPU / power modules need to be shut down for replacement.
