General
The OMD-5508SCI is a complete data acquisition system on a plug-in PC board. The OMD-5508SCI combines all the functions of external analog signal conditioning, isolation modules, module panels, power supplies, cabling, and the A/D converter into one product. The OMD-5508SCI consists of a high performance plug-in PC A/D board, and a detachable isolated screw terminal panel configured for most types of transducer inputs on a channel-to-channel basis. In addition, when used in anti-alias filtering applications, the OMD-5508SCI's filtering option completely eliminates the need for expensive external filter boxes or accessories.
Signal Conditioning
The OMD-5508SCI contains 8 (expandable to 32) high performance isolated analog inputs, user specified for transducer input type. Thermocouple, strain gage, 4 to 20 mA, ▒50 mV and ▒10 V inputs are configured on a per channel basis, allowing a custom match to user applications. As with all OMD-5508 products, the OMD-5508SCI provides a complete solution. The
OMD-5508SCI includes everything required to wire directly to the screw terminal panel. On-board cold junction compensation for thermocouples, precision bridge completion and excitation voltage for strain gages, completely eliminate the need for external accessories, or user-supplied circuitry.
Anti-Alias Filtering
For applications that have the potential for signal alias problems, the OMD-5508SCI can be ordered with integral 10 pole anti-alias filtering. Available as either Bessel or Butterworth filtering, the OMD-5508SCI
cut-off frequency is user specified from 2 Hz to 20 kHz (special order only).
Lab to Factory
The OMD-5508SCI design flexibility provides the perfect solution for both small channel I/O applications in the laboratory and large scale I/O systems for process control. Over one hundred boards can be interfaced to a single PC to create an industrial I/O system completely contained on the industry standard PC/XT/AT bus.
Signal Connection
The OMD-5508SCI board works with the
OMD-DC-SCI mating screw termination panel complete with 1500 V isolation and all necessary signal conditioning to accept transducer field wiring directly. To facilitate ease in wiring and customer use, the OMD-DC-SCI has color coded screw terminals which indicate input transducer type.
The OMD-DC-SCI isolated screw termination panel can be either mounted directly to the OMD-5508SCI board at the rear of the PC, or the user can remote the panel with the optional OMD-G37 ribbon cable.
Software Support
For those users writing their own programs, driver software is available. ADLIBPC provides the custom programmer with high level, callable subroutines that allow access to all the I/O functions on the
OMD-5508sci boards. ALDIBPC supports a wide selection of DOS based programming languages including Microsoft Fortran, Pascal, GW-BASIC, Quick BASIC, Quick C and C. Borland Turbo C, C++ and Turbo Pascal are also supported.
For an off-the-shelf software solution, the OMD-5508SCI is also supported by Labtech Notebook and Labtech Control Software.
