Introduction
The MCM-7418 board is a complete 8/16 channel analog subsystem designed to offer a simple and inexpensive way to acquire high precision sensor data for any STD based system. It is optimized for temperature and low level signal measurements and includes signal filtering, sensor excitation and linearization on all channels. The onboard CPU performs all data acquisition control and preprocesses the data, thus reducing the software overhead by the STD Bus host CPU.
Features
"Intelligent" STD Bus 8 and 16 channel sensor interface
16-Bit A/D resolution
Backward compatible with Sensoray's 7408 and 7409
Low power required
Onboard uP intelligence unburdens STD Bus system CPU by performing control, linearization, and conversion to engineering units
Pulsed excitation source reduces self-heating in resistive sensors
Supports any combination of RTD's thermocouples, strain and pressure gages, thermistors, resistors, or voltage inputs
Totally electronic calibration - no trimpots to adjust
