Din Rail 1-4 Channel Dry Contact Optic Fiber Modem

The mini type 1-4* dry contact optical Multiplexer provides 4 channel unidirectional Dry contact or 2channel bidirectional Dry contact on optical fiber transmission, which solves the problem of electromagnetic interference, the interference and the lightning damage, improve the reliability of communication, data security and confidentiality, and 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.

● Integrated circuit based on independent intellectual property rights

● Can support unidirectional 4*Dry Contact and bidirectional 2*Dry Contact

● Each channel has aDry Contact open and closed indicator light status indication

● The input Dry Contact open and closed automatically detects, when the input state is what state, the Dry Contact output is what state, which is convenient for project commissioning

● The Dry Contact is stable when it is turned on or the optical fiber is not connected, and there will be no random action state

● The DIP switch can be used to set the normally open and normally closed state of the output Dry Contact when the optical fiber is not connected

●The Dry Contact interface lightning protection reaches IEC61000-4-5 (8/20μS) differential mode: 6KV, impedance (2Ω); common mode: 6KV, impedance (2Ω) Standard

● When dual DC power supply (5.08 terminal block):

  Can be powered by DC9-55V or AC7-50V wide range power supply, the power supply has automatic polarity detection function, no need to distinguish between positive and negative poles during installation;

  Support internal isolation, redundant dual power input; anti-reverse connection protection

●  When AC power supply (three-position plum blossom AC socket):

Support AC~85-265V AC, or DC110-300V DC wide range input

● Provide DIN 35mm rail installation, or wall-mounted installation;
