2 Channel Dry Contact Closure over Fiber Optic Converter

The mini type 2ch dry contact closure over fiber converter provides 2-channel unidirectional Dry contact or 1-channel bidirectional Dry contact on optical fiber transmission, which solves the problem of electromagnetic interference, interference and lightning damage, improves the reliability of communication, data security, and confidentiality, and it can be widely used in various industrial control, process control and traffic control and other occasions, especially for banks electrical and electromagnetic interference to the environment, the special requirements of the Department and the system.

● Based on a proprietary integrated circuit;

● Enter the normally open normally closed Dry contact automatically detects when the input what state Dry contact output that is why the state to facilitate the opening of the project;

● Dry contact turned on when not connected to other Dry contact or fiber state is stable, does not appear chaotic action status;

● Dry contact interface Lightning reach IEC61000-4-5 (8 /20μS) differential mode: 6KV, impedance (2Ω); Common mode: 6KV, impedance (2Ω) standard;

● Optional AC 220V, DC -48V, DC + 24V, DC power no positive and negative points;

● Fiber
