Industrial grade 16ch serial/32ch dry contact fiber mux

    It provides up to 1-16 serial ports or 1-32 one-way switching values or 16 two-way dry contact or a combination of both (the ratio of serial port to dry contact is 1:2) for transmission in optical fiber. This product solves the problems of electromagnetic interference, ground ring interference and lightning damage, improves the reliability, security and confidentiality of data communication, and can be widely used in various industrial control, process control, traffic control and other occasions, It is especially suitable for banks, electric power and departments and systems with special requirements for electromagnetic interference environment.

●provide up to 1-16 serial ports or 1-32ch dry contact or 16 two-way dry contact or a combination of both (the ratio of serial port to dry contact is 1:2);
●the dry contact can support one-way 32 channel dry contact and two-way 16 channel dry contact; The dry contact type supports dry node and wet node;
●each circuit has on-off and on-off indicator light status indication; The opening and closing of input dry contact are automatically detected. When what state is input, the switching value output is what state;
●when the dry contact is turned on or the optical fiber is not connected, its switching state is stable and there will be no disordered action;
●The dry contact input interface is equipped with a filter to filter out interference pulses and ensure the stable output of switching value signal at the output end;
●the normally open and normally closed states of each switching output when the optical fiber is not connected can be set;
●the serial port supports three optional data interfaces: RS232 / 485 / 422, and RS232 supports 3-wire RS232 (TXD, RXD, GND);
●RS232 / 485 / 422 channel can transmit asynchronous self-adaptive serial port data from 0-115200 baud rate;
●the lightning protection of serial port and switching value interface shall reach iec61000-4-5 (8 / 20) μ S) Differential mode: 6kV, impedance (2 Ω); Common mode: 6kV, impedance (2 Ω) standard;
●support a wide range of 9-55v AC and DC power input;
●support internal isolation and redundant dual power input;
●the power supply supports overload protection and anti reverse connection protection;
●meet the requirements of industrial level IV electromagnetic compatibility;
●super lightning protection function: lightning protection, anti induced high voltage, anti surge, etc;
