The switch quantity problem of the optical transceiver can be said to be one of the common problems of the optical transceiver, which has a relatively large impact on the monitoring effect. Then, how should we solve the switch quantity problem of the optical transceiver? Next, the editor of Hangzhou Feichang Technology will explain it in detail for everyone, and interested friends will come to understand it together!
The switch signal is a TTL level pulse train, which can control the work of warning lights, alarm bells, relays, etc. The load capacity of the switch interface is measured by the magnitude of the controlled current, such as the switch load capacity of the switch optical transceiver is 1.5 A.
The switch interface of the industrial rail optical transceiver supports the normally open button, but when connected as shown in the figure below, both the normally open and normally closed modes are supported. The digital interface cannot be used directly in parallel, and can only be connected through the distribution circuit if necessary.
Some customers use the RS-485 bus to transmit switching values. According to our practical experience, this method is not advisable, and there will often be a crash after working for a period of time (such as 3 to 4 days). The defective production of the switch to RS-485 converter may be the problem.
Well, the above content is about how to solve some simple methods of the switch problem of the optical transceiver, I hope it can help everyone. Feichang Technology has been engaged in the R&D, production and sales of industrial communication equipment such as optical transceivers, industrial switches, optical fiber transceivers, and protocol converters for 20 years. Welcome to come to understand and exchange ideas.
