Din Rail 1-4 Channel Dry Contact Optic Fiber Modem

● 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;
