ExpertDAQ EX9000 module families
The manufacturer sorts the EX9000 modules by function: converters, digital input and output modules, relay and solid state output modules, analog input and output modules, and counter and frequency modules. They communicate on RS-485 using Modbus RTU, and a separate group of MTCP models has an Ethernet port. The EX9188 series are small embedded controllers that can run a program locally. A typical small system uses one EX9520 to connect the RS-485 line to a serial port and a row of I/O modules behind it.

Ordering ExpertDAQ modules: what we need
Send the full model number with every suffix letter, since suffixes separate versions with a display, a faster input or a different protocol. State the protocol your software expects, the signal types and ranges, and the number of channels. For expansions of existing panels in the GCC, tell us the modules already on the bus so the new ones are requested with compatible settings.

FAQ
Questions about ExpertDAQ
Common questions about ExpertDAQ equipment, part numbers and supply to Oman and the GCC.
01What do the suffix letters in an ExpertDAQ model number mean?
They mark variants of the same base module. In the listed models, EX9017F, EX9044D and EX9188E5-M each carry a suffix that sets the version. The meaning differs between module types, so check it in the manufacturer's datasheet for that base number, and always order with the full number printed on the module label.
02Which protocol do ExpertDAQ EX9000 modules use?
The manufacturer describes the EX9000 I/O modules as RS-485 modules using Modbus RTU, and offers MTCP models with an Ethernet connection. Because the protocol option can depend on the exact model and suffix, tell us what your SCADA or PLC driver expects so the version requested will talk to it.
03How many signals does the EX9017F handle?
It is listed as an eight channel analog input module on RS-485. The accepted signal ranges are set per the manufacturer's datasheet. Send us the sensor outputs you need to read, in millivolts, volts or milliamps, and we will check them against the datasheet before the module is ordered.
04Do I need the EX9520 converter?
You need a converter when the host computer or controller has an RS-232 port and the modules are on RS-485. The EX9520 is listed as an isolated RS-232 to RS-485 converter for that job. If your host already has an RS-485 port, or you use Ethernet models, it is not required.
05Is Seven Star LLC a distributor of ExpertDAQ?
No. Seven Star LLC is an independent supplier and is not a distributor or agent of ExpertDAQ or TOPSCCC. We source ExpertDAQ modules and converters through commercial channels, check the model or order code against the manufacturer's documentation before ordering, and provide the manufacturer's datasheet and the certificates the manufacturer issues with the order on request.
