Data Acquisition System

Faulty thousand-dollar data acquisition systems can shut down billion-dollar operations. The SCM5B isoLynx® SLX200 is a fast, intelligent, fully isolated data acquisition system providing superior reliability, accuracy, and isolation for a wide range of rugged industrial applications. It offers maximum-flexibility of analog and digital I/O selection at competitive prices for a broad range of factory automation, process control, test and measurement, machine control, and data acquisition applications. The isoLynx SLX200 implements the industry standard Modbus® RTU and TCP protocols, thereby enabling communication with a wide variety of existing third-party software drivers and HMI/SCADA packages. It is fully certified by Modbus-IDA and compatible with OPC.

All I/O Channel-to-Channel Isolated
The flexible, modular design combines a 6- or 12-channel I/O Controller base system and optional 8- or 16-channel expansion backplanes, which can be either panel or DIN rail mounted (see Figure 1).

One I/O Controller unit can operate up to 60 channels of differential analog I/O and 128 channels of digital I/O, using Dataforth’s SCM5B an- alog and SCMD digital modules. The Controller contains a powerful high- speed microcontroller, A/d D/A subsystem, communication interface, data storage memory, and status LEDs. The A/D system is built around a 16-bit, successive approximation converter and can convert a maximum 60-channel configuration in 17msec. The D/A converter is also a 16-bit device and can write a maximum 60-channel configuration in 33msec.
