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 device under the adverse environment, 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.
Ø Support point-to-point network topology
Ø Provide two optical interfaces, 1 + 1 optical interface protection (APS)
Ø The electric interface is powered by independent power supply module, which completely isolates the ground circuit between bus and 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 power supply ground circuit and surge.
Ø Support 32 channel unidirectionaldry contact or 16 channel bidirectional dry contact
Ø There are indicators oneach channel to show on or off of the dry contact
Ø Automatically detect on and off of day contact closure, the output is what the input state, with convenience of the project
Ø When the dry contact closure is on or the optical fiber is not connected, the switch state is stable and there will be no disorderly action
Ø Input interface self-band filter can filter out interference pulse and ensure stable output signal of output terminal
Ø Can set the open and closed states of each channel when the optical fiber is not connected
Ø Lightning protection can reach IEC61000-4-5 (10/ 700μS) differential mode: 6KV, impedance (2Ω); Common mode: 6KV, impedance (2Ω) standard
