The relay uses Omron, one of the best brands
The cost control and type selection of PLC depend on I / O module, which is an important part of PLC. The biggest weakness of PLC is I / O port. The technical advantage of PLC lies in its I / O port. In the case that the technical level of host system is different, I / O module is the key component to reflect the performance of PLC, so it is also a prominent link in PLC damage. The relay used by Gu Mei is Omron, one of the top ten brands in the world.
Special protection of communication port
RS-232 interface has low data transmission rate, limited transmission distance and poor anti-interference ability. RS-422 adopts full duplex communication mode and differential transmission mode to enhance the anti-interference ability of common mode. Gu Mei uses 485 port, which has higher pressure resistance than 232 port and is not easy to burn out.
Through these methods, the failure rate of PLC is greatly reduced, and the volume of PLC is smaller, but the performance is better. These applications in customers have always been recognized by customers.
