REMOTE ACCES 12-Bit Analog/Digital I/O Pod
RAD128 is an intelligent, eight channel, 12-bit, analog-to-digital converter unit that interfaces to a host computer through an optoisolated asynchronous serial port. It is packaged in a steel enclosure for remote installation and input connections are via screw terminals on the card. Communication with the host computer is via EIA RS485 serial communications. ASCII-based command/response protocol permits communication with virtually any computer system that has an RS485 port. ASCII-based programming permits you to write applications in any high-level language that supports ASCII string functions. As many as 31 RAD128's may be connected on a single two or fourwire multidrop network. Each unit has a unique address and communication uses a master/slave protocol wherein the unit talks only if questioned by the computer.
Features
Remote intelligent analog and digital I/O unit with opto-isolated RS-485 serial interface to host computer
Eight-channel programmable gain, 12-bit resolution A/D converter
Can be used with AIM-16 multiplexer to support up to 128 differential or single ended inputs
Eight digital I/O lines, bit-programmable as inputs or outputs
Protective Nema4 enclosure for harsh atmospheric and marine environments(RAD128 only)
8031 microcontroller with 8 x 32K RAM and 8 x 32K EEPROM
On-board crystal clock and three 16-bit counter/timers
Watchdog circuit for reset on power-up and microprocessor failure
All programming in software, No switches to set. Jumpers (3) to by-pass opto-isolators if desired.
