Remote Acces 24-Bit Analog/Digital I/O Pod

RAD242

Model RAD242 is an intelligent, two-differential-channel, 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. A built-in watchdog timer resets the pod if, for some unexpected reason, the microcontroller “hangs up” or if the power supply voltage drops below 4.75 VDC. Data collected by the pod is stored in local RAM for later access through the computer’s serial port. This feature facilitates a stand-alone mode of operation. For example, a portable or laptop computer that has an RS-485 port can be brought to the pod, connected, and collect the data.
