Selection and usage precautions

（1） Selection principle

Scene matching:

If it is driving and controlling high-voltage power equipment (frequency converter, inverter), priority should be given to 5SHY35L4503;

If it is for centralized control of small and medium-sized equipment (such as rolling mill auxiliary equipment, water treatment unit), the 3BHB series can be selected;

If it is a large-scale production line or power station control, 5SXE01-0127 should be selected to meet the requirements of multi device collaboration and high-speed computing.

Parameter adaptation:

Confirm that the working voltage matches the on-site power supply (e.g. 5SXE01-0127 supports AC110/220V, 3BHB series is DC24V);

The number of interfaces should cover the number of sensors and actuators on site (such as 3BHB004692R0001's 24 channel input adapted to multi-sensor scenarios);

The communication protocol needs to be compatible with existing systems (such as PROFINET adapted to Siemens systems, Modbus RTU adapted to general-purpose PLCs).

（2） Installation and maintenance recommendations

Installation requirements:

All main control boards must be installed inside a metal control cabinet to avoid direct sunlight and dust accumulation;

Reserve a heat dissipation gap of ≥ 10mm between the boards, and a heat dissipation fan is required for high temperature environments (such as metallurgical workshops);

When wiring, distinguish between strong current (power circuit) and weak current (control circuit) to avoid electromagnetic interference (it is recommended to use shielded cables).

Maintenance points:

Regularly (every 3 months) read the status of the board through the communication interface and troubleshoot alarm information;

Clean the board once a year (use compressed air to blow away dust, do not wipe with water or alcohol);

The firmware upgrade should follow the process of "power-off backup online upgrade restart verification" to avoid system paralysis caused by upgrade failure.
