●2 optical interfaces support 1+1 optical backup. When the main optical fiber is broken, it switches to the backup optical fiber. When the main optical fiber is normal, it switches to the main optical fiber. The switching time between the main and backup optical fibers is less than 1ms. The switching of optical fibers does not affect the state of the dry contactbeing transmitted.
● There are 16 module slots in the device, with 2 analog quantities per slot, which can be bidirectional, 2 dry contact per slot, which can be bidirectional, and 1 serial port per slot. For example, it can be made into an optical terminal with 8 bidirectional analog quantities + 8 unidirectional dry contact+ 4 serial ports.
● The analog quantity supports 4~20mA current quantity; or 0~10V/0~5V, voltage quantity; 32 analog input and output can be combined arbitrarily;
● The AD/DA channels of the 32 analog quantities use FPGA parallel reading and writing, not MCU sequential reading and writing mode, and the delay of each analog quantity is less than 0.1ms;
● Each analog quantity reads high-speed sampling data through FPGA, and the sampling rate is 20K times/second, much higher than similar products on the market;
● After the analog output end with optical fiber is broken or the input end device loses power, the analog output maintains the value before the most recent fiber break, and is enabled by DIP switch setting. When this function is not enabled, the analog value after fiber break is 0MA, or 0V;
● The serial port supports three data interfaces RS232/485/422, RS232 supports 3-wire RS232 (TXD, RXD, GND); RS232/485/422 channels can transmit asynchronous serial data with adaptive baud rate from 0-115200
● Each dry contacthas an open and closed indicator light status indication; the DI is automatically detected when it is open and closed, and the DO is in the same state when the input is in any state, which is convenient for project activation; the switch state of the dry contact is stable when the power is on or the optical fiber is not connected, and there will be no random action state;
● Multi-mode fiber/single-mode fiber is optional, multi-mode can transmit 2KM, single-mode can transmit 20KM, ST/SC/FC Optional interface;
