● The device is used in pairs, the signal input of the local end, and the signal output of the opposite end;
● Support 4~20mA, 1-8 channels of current; or support 0~10V/0~5V, 1-8 channels of voltage; 8 channels of analog input and output can be combined arbitrarily;
● The AD/DA channel of 8 analog quantities adopts FPGA parallel reading and writing, non-MCU sequential reading and writing mode, and the delay of each analog quantity is less than 0.1ms;
● Each channel of analog reads high-speed sampling data through FPGA, and the sampling rate is 20K times per second, which is much higher than similar products in the market;
● Multi-mode fiber/single-mode fiber is optional, multi-mode can transmit 2KM, single-mode can transmit 20KM, ST/SC/FC interface is optional;
● With signal fault protection function; all-round display of electrical interface and optical fiber operating status
● 4-20ma interface anti-radar to IEC61000-4-5 (8/20μS) differential mode: 6KV, impedance (2Ω); common mode: 6KV, impedance (2Ω) standard;
● Serial port supports RS232/485/422 three kinds of data interface optional, RS232 supports 3-wire RS232 (TXD, RXD, GND);
● RS232/485/422 channels can transmit asynchronous serial port data adaptive from 0-115200 baud rate
● The dry contact can support one-way 8-channel dry contact and two-way 4-channel dry contact, and each channel has an indicator light indicating whether the dry contact is on or off;
● The input dry contact is automatically detected on and off. When the input state is, the dry contact output is in that state, which is convenient for project opening;
● The switching state of the dry contact is stable when it is turned on or the optical fiber is not connected, and there will be no disorderly action state;
● Support a wide range of AC and DC input, support internal isolation, redundant dual power supply input, power supply supports overload protection, anti-reverse connection protection;
● Comply with industrial level 4 electromagnetic compatibility requirements;
● Super lightning protection function: lightning protection, anti-inductive high voltage, anti-surge, etc.;
● No fan for efficient heat dissipation, reducing repair time;
● IP40 shell protection level, able to withstand the test of harsh environments;
● Rail or wall-mounted installation;
● Wide temperature type: working temperature -40℃~ +85℃;
● All models have passed 100% burn-in test, warranty period: 5 years.
