AiM RIO 02 Remote Input/Output Module for PDM
The AiM RIO 02 is a remote input/output module for compatible AiM PDM systems. It adds configurable push-button inputs when the available PDM inputs are not enough, allowing the PDM system to receive more switch commands from around the vehicle.
The inputs can be configured for momentary, two-position, and multi-status controls, including separate short- and long-push behaviour where supported by the system configuration. The RIO 02 also provides two low-side digital outputs.
What is confirmed
- PDM role: Remote expansion for push-button and switch management.
- Inputs: 19 inputs, listed as 8 programmable switch-to-battery inputs and 11 switch-to-ground inputs.
- Outputs: Two low-side digital outputs, maximum 2 A each.
- Communication: One CAN connection is listed.
- Housing: Plastic body.
- Weight: 129 g.
- Connector information in the source record: A 5-pin 712 male connector and an AMP 776087-1 connector are listed. Confirm the connector assignment, mating parts, pinout, power, ground, and CAN wiring against the correct AiM documentation before installation.
This module is an input/output expansion accessory. It is not a standalone PDM, ECU, data logger, dash, or universal CAN controller.
Fitment and installation checks
- Confirm that the connected AiM PDM supports the RIO 02 and the required expansion configuration.
- Plan the switch-to-battery and switch-to-ground circuits before wiring the module.
- Confirm the input configuration for momentary, two-position, and multi-status switches in Race Studio 3.
- Verify the CAN wiring, power, ground, connector assignment, pinout, and termination requirements.
- Keep each low-side output within the stated 2 A maximum and confirm whether a load requires additional protection or a relay.
- Protect the module and wiring from heat, abrasion, moisture, and moving components.
- Test every switch input and output function with the vehicle stationary before competition use.
