Product advantage:
1, the second generation of Mornsun 3000V isolation voltage module, better performance. Isolation voltage from 1500V upgrade to 3000V, more secure;
2, ultra high-speed optical coupling chip, to meet the communication needs of high baud rate;
3, dual serial port input interface circuit, the use of multi-level protection cascade (TVS + RC filter), all for the design of industrial environment;
4, general guide rail housing, the use of more convenient
5, +12~24V DC voltage supply input, anti - Anti - ground protection.
6, improve the simulation output protection, 1000V anti intrusion protection, anti surge plus 600W TVS tube, the use of more security module;
7, standard MODBUS-RTU interface, to adapt to all the PLC module connection;
8, 12 bit DAC chip, 12 bitADC chip, accurate analog output;
9, the baud rate range: 300 ~ 115200bps (also more special requirements please);
10, all industrial design, to ensure that the use of new imported chips; temperature range: -40 degrees to 85

| input | Output range | Resolution power | Accuracy | Explain |
| Electric current | 0.000~22.000mA | 0.001mA | .0.05 mA | Sampling resistance 100 ohm |
| Voltage | 0.000~-12.000V | 0.001V | .0.05V | Impedance 10K |
CRC-16 (BISYNCH, polynomial is x16 + x15 + x2 + 1 shield word for 0A001H)
Cyclic redundancy algorithm is obtained. Please refer to the MODBUS for further information about the algorithm.
The returned data should be:
| 01 | 06 | 0001 | 01 F4 | D8 1D |
| Equipment number | Write function | Register address | Register value | check |
l Read register --03
Read 2 device channel 1 and channel 2 of the current input value, 0x0005, 0x0006 two Register commands are as follows:
| 02 | 03 | 0005 | 0002 | D4 39 |
| Equipment number | Read function | Register address | Register number | check |
Return data:
| 02 | 03 | 04 | 013202 2A | E9 BF |
| Equipment number | Read function | Number of bytes | data | check |
Among them, the channel 0132 is the value of 1 0x0132, decimal number is 306, then the input value is 306/100 =3.06, the same calculation method,
Can calculate the channel 2 input values.
