● Optical port transmission distance without repeaters can reach 2-120 kilometers; provides 1+1 optical port backup function, dual optical port backup ensures uninterrupted service (optional);
● The device has a total of 2 module slots, each slot has 2 analog channels (bidirectional), 2 dry contact channels (bidirectional), or 1 serial port channel, for example, it can be configured as 1 bidirectional analog channel + 1 unidirectional dry contact channel;
● Analog signals support 4-20mA current; or 0-10V/0-5V voltage; 16 analog input and output channels can be arbitrarily combined;
● The 4 analog AD/DA channels use FPGA parallel read and write, not MCU sequential read and write mode, and the delay of each analog channel is <0.1ms;
● Each analog channel reads high-speed sampled data through FPGA, with a sampling rate of 20K times/second, far higher than similar products on the market;
● When the fiber is broken or the input device is powered off, the analog output maintains the value before the fiber break. This function is enabled by a DIP switch. When this function is not enabled, the analog output is 0mA or 0V after a fiber break;
● The serial port supports RS232/485/422 three data interfaces, RS232 supports 3-wire RS232 (TXD, RXD, GND); RS232/485/422 channels can transmit asynchronous serial data with adaptive baud rates from 0-115200;
● Each dry contact channel has an indicator light to show the open and closed status; the dry contact input signal is automatically detected, and the dry contact output signal matches the input state, facilitating engineering commissioning; the dry contact signal remains stable in the power-on state or when the fiber is not connected, without erratic behavior;
● Multimode fiber/single-mode fiber is optional, multimode can transmit 2KM, single-mode can transmit 20KM, ST/SC/FC interfaces are optional;
● It has signal fault protection function; comprehensive display of electrical interface and fiber operation status;
● 4-20mA interface lightning protection meets IEC61000-4-5 (8/20μS). Differential Mode: 6KV, Impedance (2Ω); Common Mode: 6KV, Impedance (2Ω) Standard
●When using dual DC power supply (5.08 terminal block):
Supports wide range power supply of DC 9-55V or AC 7-50V, with automatic polarity detection function, no need to distinguish between positive and negative poles during installation;
Supports internal isolation and redundant dual power input; reverse connection protection;
● When using AC power supply (three-pin AC connector):
Supports AC 85-265V or DC 110-300V wide range input;
●Complies with industrial level 4 electromagnetic compatibility requirements;
●Super strong lightning protection function: lightning strike protection, resistant to induced high voltage, surge protection, etc.; fanless high-efficiency heat dissipation, reducing repair time;
● IP40 enclosure protection rating, able to withstand harsh environments;
● DIN rail or wall mounting; wide temperature range: operating temperature -40℃~ +85℃;
● All models have passed 100% burn-in testing, warranty period: 5 years;
