With the development of industrial automation, PLC (programmable logic controller) has been widely used in various industries of production equipment to achieve a variety of automatic control. The application of PLC in radio frequency welding equipment is relatively late. This is mainly because the electric field radiation of the high frequency equipment can cause the work interference and even puncture the damage to the micro-electronic equipment.
The application of PLC in high frequency equipment mainly lies in the shielding system of the equipment and the auxiliary protection circuit of the system. It is risky to install a PLC system on a high frequency device with no tight shielding. Long-term application of interference can lead to chaos of the PLC system, unstable parameters and frequent damage to core components.
The environmental energy efficiency of high frequency equipment is not replaceable by other devices, provided that there are close screening, filtering, bypass and isolation protection circuit. When selecting high frequency equipment, must not focus on production function. Without perfect shielding and protective circuits, high frequency devices will become a source of pollution and invisible killers.
