Electrical control cabinets can employ traditional relays or PLC (Programmable Logic Controller) control. Relays are typically used for simpler control tasks, while PLCs are employed for more complex control scenarios. PLCs allow for programmable logic control. Control cabinets equipped with large-screen LCD displays provide a more effective and intuitive visualization of various process tank parameters and the status of the electrophoresis line. This enhanced visual representation improves user experience and facilitates operation.
