The RAD-IO2 series is a family of ruggedized products that provide an isolated analog, digital or temperature interface to a PC via the PC’s USB port. These tools can also be paired with Intrepid products that include a USB port such as neoVI ION, neoVI FIRE 2, RAD-Galaxy, and RAD-Gigalog. In addition, the RAD-IO2-CANHUB can power and convert the native UART signal to CAN or CAN FD for use in any CAN device.

The RAD-IO2 family communicates on an open source UART based serial communication protocol. Up to eight devices can be daisy chained. The chain length is limited by current supplied to the chain through USB. All RAD-IO2 devices have input to output isolation, and 2.5kV isolation between each of the eight banks. Bank to bank isolation is important because it allows the common mode voltage of each input signal to be different than the other channels in other banks. (This is a major source of measurement error and can damage to the product.) Additionally, noise on one channel will not affect other channels.

Product Family

  • RAD-IO2-TC: 8 Isolated banks, each with 1 isolated channel of K-type thermocouple
  • RAD-IO2-AIN: 8 Isolated banks, 1 channel per bank selectable between a high or low voltage input
  • RAD-IO2-AOUT: 8 Isolated analog output banks, each with 3 analog outputs per bank
  • RAD-IO2-PWRRLY: 8 Isolated SPDT (single pole double throw) electro-mechanical relays
  • RAD-IO2-DIO: 12 digital/analog inputs and 8 digital outputs
