General Description:
JSD AD11 series products realize the signal acquisition between sensor and host, to measure analog signals. JSD AD11series products can be applied to RS-232/485 bus industrial automation control system, 4-20mA / 0-5V signalmeasurement, monitoring and controlling, 0-75mV, 0-100mV and other small-signals measurement and signals isolationand long-term industrial transmission and so on. Products include power supply isolation, signal isolation, linearization,A/D conversion and RS-485 serial communication. Each serial interface can connect up to 255 pieces JSD AD11 Seriesmodules, communication using ASCII code or MODBUS RTU communication protocol, and its instruction setcompatible with the ADAM modules, baud rate can be set by the code, with other manufacturers control module hang inthe same RS-485 bus for easy programmingPicture 2: JSD AD11 module internal block diagram Analog signals to RS-485/RS-232 data acquisition A / D converter JSD AD11 seriesThe copyright and products interpretation own to Shenzhen Jie Sheng Technology Co., Ltd. products update without noticeShenzhen jieshengda Technology Co., Ltd.Coofficial
JSD AD11 series is based on SCM intelligent monitoring and control system, all of the users set configurationinformation such as Calibration value, address, baud rate, data format, checksum and status are stored in non-volatilememory EEPROM.
JSD AD11 series products according to industry standard design and manufacture .They are three-port isolation(input,output and power supply),and the isolation voltage between them is up to 3000 VDC, JSD AD11 series products havebetter Anti-interference ability, high reliability and wide operating Temperature Range (- 45ºC~+85ºC.)Function Description:JSD AD11 signal isolation acquisition module can be used to measure one channel voltage or current signal,
1. Analog signal input12-Bit acquisition accuracy, all products signal input range have been calibrated. In using, users also can programCalibrate easily. About the specific current or voltage input range, please see product selection.
2. Communication protocolCommunication Interface: one channel standard RS-485 communication interface, or one channel standard RS-232Communication interface, specify when ordering.Communication Protocols: supports two protocols, characters protocol of the command set defined and MODBUSRTU communication protocol. Can be programmed using the kind of communication protocol, can be achieved withPLC, RTU of many Brands or computer monitoring system for networking communication.Data Format: 10 Bits. 1 start bit,8 data bits,1 stop bit.Address: (0 to 255) and baud rate (1200,2400,4800,9600,19200,38400bps) can be set, the most long-distance aboutcommunication networks is up to 1200 meters, through the twisted-pair shielded cable.Communication interface of high anti-jamming design, ± 15KV ESD protection, communication response time is lessthan 100mS.
3. Anti-jammingAccording to need to set the checksum. Module internal has transient suppression diodes, can inhibit a variety of surgepulse, protection module, and internal digital filter can also be well suppressed from the grid frequency interference.
