REMOTE ACCES 24-Bit Analog/Digital I/O Pod
Model RAD242 is an intelligent, two-differential-cha
nnel, 24-bit analog-input interface unit that includes a Delta-Sigma A/D converter. The converter has a digital output filter with adjustable notch frequency from 10 Hz to 2000 Hz. The pod also has 13 bits of digital input/output. A precision 10 VDC voltage that can be used for transducer excitation is available at connector pin 5. As much as 60 mA current can be provided. It is packaged in a NEMA 4 enclosure for remote installation in harsh environments. RAD242 also provides a user-definable interrupt input and counter/timer input. An optional RAD Firmware Development Kit is available if you wish to use those user-programmable input lines or to develop a custom program.
Features
Remote intelligent A/D I/O unit with opto-isolated RS-485 interface to host computer
NEMA 4 enclosure for harsh atmospheric and marine environments
Type 8031 microcontroller with 32K x 8 bits RAM and 32K x 8 bits EEPROM.
Two-channel 24-bit A/D delta-sigma converter
Bi-polar and unipolar voltage input ranges of 2.5 V and 5 V
Self-calibrating or auto-calibrating modes to eliminate drift errors
13-bit digital port with each bit programmable as either input or output
Constant current source for thermocouple cold-junction compensation
Precision 10 VDC excitation for transducers
All programming in software, almost no switches.
