RA1216 Remote


RA1216 Remote Data Acquisition Pod

Main Features:

  • Remote intelligent analog and digital I/O unit with opto-isolated RS-485 serial interface to host computer
  • Eight differential or sixteen single-ended analog inputs, programmable gain and offset on a channel-by-channel basis, 12-bit resolution A/D converter. Programmable gains provide spans between 5VDC and 25mVDC
  • Optional signal conditioning for use with thermocouples, RTDs, 4-20 mA current inputs, and resistors for strain gage bridge completion.
  • Three 12-bit D/A converters with both voltage and current outputs.
  • Seven bits of digital I/O configured on a bit-by-bit basis as either inputs or high-current outputs.
  • Onboard 16-bit, 8031 compatible microcontroller with 32K RAM and EEPROM
  • Watchdog circuit for reset on power-up and microprocessor failure
  • All programming and calibration in software, No switches to set. Jumpers (3) to by-pass opto-isolators if desired.
  • Protective Nema4 enclosure for harsh atmospheric and marine environments

Digital I/O:

  • Number of Bits: Seven parallel bits. each is software configured to be input or output.
  • INPUT:Logic Low: -0.5 to 0.8 VDC at -0.4 mA max.
  • INPUT:Logic High: 2.0 to 5.0 VDC (5mA max at 50V in)
  • Logic-Low Sink Current: 350 mA maximum. Inductive-kick suppression diode included in each circuit.
  • High-Level Output Voltage: Open collector, compliance with up to 50V user-supplied voltage. If no user-supplied voltage exists, outputs are pulled up to +5VDC via 10 kilohm resistors.


  • Operating Temperature Range: 0° to 65°C. (Optional -40°C to +80°C.)
  • Storage Temperature Range: -20°C to +120°C.
  • Humidity: 5% to 95% RH, non-condensing. Enclosure is designed to meet NEMA 4 requirements.

Power Required:

  • Power for the opto-isolated section can be applied from the computer's +12 VDC power supply via the serial communications cable, if a four-wire cable is used, or by a local isolated power supply. Power for the rest of the pod can be provided by a local power supply.
  • Opto-Isolated Section: 7.5 to 25 VDC @ 40 mA maximum (7 mA at 12 VDC .)
  • Local Power: 7.5 to 16 VDC at 250 mA (typical).


Regulatory Compliance:

  • This product is in full compliance with CE requirements.
