Input we have 4-20ma,0-20ma,0-5v,0-10v,
please note when order,default is 0-10V

ZL-522 isoLation dual serial transfer analog module (232 & 485 rpm 0-10V 4-20mA)

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, temperature drift is only 2ppm/ degrees C TI imported original 2 16 DAC chip, chip price over 30 yuan, 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

l Supply voltage: +12~24V DC voltage (12V power supply is weak), the power supply reverse protection;

l Communication interface: optocoupler isolation 3000 VDC, single 600W surge protection;

l Communication protocol: using RTU Modbus communication protocol;

l Zero drift: + 0.2uA/;

lWrite single register --06

For example, channel 1 of the channel 1 analog output, that is, write the register 0x0001, the order is as follows:

01	06	0001	01 F4	D8 1D
Equipment number	Write function	Register address	Register value	check

Among them, the set of analog data is 01 F4, that is, 0x1F4, decimal number is 500, then the output value of I=500/1000 = 0.5ma;

1D D8 is the 16 decimal value, is in accordance with CRC-16 (BISYNCH), the polynomial is x16 + x15 + x2 + 1 shield word is 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 1 is the value of 0132 0x0132, the decimal number is 306, then the input value is 306/1000 = 0.306, the same calculation method,

Can calculate the channel 2 input values.
