8- to 16-channel inputs, each channel, height-isolated, tamper-resistant smart sensor modules: ISO AD08 / ISO AD16 series

     ISOAD series products are intelligent monitoring and control systems based on microcontrollers. All user-set configuration information such as calibration values, address, baud rate, data format, checksum and status are stored in non-volatile memory EEPROM.  

      ISOAD series products realize safe signal isolation and high-precision digital acquisition and transmission between sensors and hosts, and are widely used in RS232/485 bus industrial automation control systems, 4-20mA / 0-5V signal measurement / Pt100 and other RTD measurement monitoring and control, small signal measurement, as well as signal isolation in the industrial field and long-wire transmission, and other remote monitoring occasions. Through the software configuration, you can access a variety of sensor types, including current output type, voltage output type, and thermocouples and so on.

        The product internally includes functional modules such as power isolation, signal isolation, linearization, A/D conversion and RS-485 serial communication. Each serial port can be connected to a maximum of 256 ISOAD series modules, the communication method adopts ASCII code character communication protocol or MODBUS RTU communication protocol, its instruction set is compatible with ADAM module, baud rate can be set by the user, can be hooked up to the same RS-485 bus with the control module of other manufacturers, which is convenient for the host computer to program.ISOAD series of products according to the industrial standards of design, manufacture, signal input / output isolation, can withstand 3000VDC isolation voltage, anti-interference ability. ISOAD series products are designed and manufactured in accordance with industrial standards, and the signal input/output is isolated from each other, which can withstand 3000VDC isolation voltage, with strong anti-interference ability and high reliability. Wide operating temperature range - 25℃～+70℃.

Function Overview 

The ISO AD signal isolation acquisition module can be used to measure up to 16 channels of isolated/non-isolated current or voltage signals.

1、 Analog signal input 

Maximum 16 channels, 24-bit acquisition accuracy per channel, each channel has been calibrated before leaving the factory. When using, users can also easily program their own calibration. 

Please refer to the product selection table for current or voltage input range, all channels must have the same input signal type and range, i.e. the same voltage or current type.

2、 Communication protocol 

Communication interface: the product has RS485/232 automatic selection of output function, a standard RS-485 communication interface or a standard RS-232 communication interface, only one way is valid when using. 

Communication protocol: It supports two protocols, special ASCII character communication protocol and standard MODBUS RTU communication protocol, which can be programmed. It can realize network communication with many brands of PLC, RTU or computer monitoring system. 

Data format: 10 bits. 1 start bit, 8 data bits, 1 stop bit. 

Checksum: Checksum can be set as required. 

Communication address: (0~255) 

Baud rate: (300, 600, 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200bps) can be set by the user; RS-485 mode, connected by twisted shielded cable, the longest communication distance can reach 1200 meters. 

Communication interface high anti-interference design, ±15KV ESD protection, communication response time less than 100Ms/per channel.

3、 Anti-interference 

The module has transient suppression diodes inside, which can effectively suppress various surge pulses and protect the module. Embedded digital filtering, can be very good suppression of industrial frequency interference from the power grid. 

Remarks: RTD products can do up to 10 channels, 4-20mA or 0-5V common signal can be done 16 ways, each channel isolated analog input, RS485/232 automatic selection of the output, the user can be connected to different communication ports to directly select the RS485 output or RS232 output. 

Selection example 1: Model ISO AD16 A4-485; ISO AD: each input channel isolation type; A4-485: 4-20mA input, output RS485 interface 

Selection example 2: Model ISO AD10 Z1 W2-232; ISO AD: each input channel isolation type; Z1W2-232: Pt100 RTD signal input, range 0 - 100 ℃, output for R S232 interface
