Dry Contact Closure over Fiber Converter (32Ch Unidirectional/16Ch Bidirectional)

This device provides 1-32 channel unidirectional dry contact or 16 channel bidirectional dry contact. As a result of the fiber as a transmission medium, you can completely avoid the threat to communication devices under adverse environments, such as lightning, surges, and electromagnetic interference, to improve the reliability, security, and confidentiality of data communication.

It can be widely used in various occasions, such as industrial management, process management, and traffic management,  especially for banks, electric power, and some departments who has special requirements for electromagnetic interference environment.

● Support point-to-point network topology

● Provide two optical interfaces, 1 + 1 optical interface protection (APS)

● The electric interface is powered by an independent power supply module, which completely isolates the ground circuit between the bus and the equipment. At the same time, the photoelectric isolation technology is used to isolate the internal communication and bus data signals, which effectively protects the communication equipment from the interference of the power supply ground circuit and surge.

● Support 32-channel unidirectional dry contact or 16-channel bidirectional dry contact

● There are indicators on each channel to show on or off of the dry contact

● Automatically detect on and off of-day contact closure, the output is what the input state, with the convenience of the project

● When the dry contact closure on or the optical fiber is not connected, the switch state is stable and there will be no disorderly action

● Input interface self-band filter can filter out interference pulse and ensure stable output signal of the output terminal

● Can set the open and closed states of each channel when the optical fiber is not connected

● Lightning protection can reach IEC61000-4-5 (10/ 700μS)  differential mode: 6KV, impedance (2Ω); Common mode: 6KV, impedance (2Ω) standard
