IOcan Electrical Characteristics¶
This page describes the electrical characteristics of the IOcan hardware, including power consumption, input measurement ranges, and electrical limitations.
For connector pin assignments see:
Power Supply¶
IOcan is designed for permanent installation in automotive electrical systems and supports continuous connection to battery power.
Supply Voltage¶
| Parameter | Value |
|---|---|
| Operating voltage | 9–16 V |
| Recommended nominal voltage | 12 V automotive system |
The device should be powered directly from the vehicle battery through a fused supply.
Recommended fuse for vehicle installations: 30 A.
Quiescent Current¶
IOcan is optimized for low standby power consumption.
| Mode | Typical Current |
|---|---|
| Standby (KL30 only) | < 0.5 mA |
| Active operation | depends on connected loads |
The low standby current allows the device to remain permanently connected to battery power without significantly draining the vehicle battery.
Transmission Power Output (KL30B)¶
IOcan includes an integrated semiconductor power switch used to power the transmission.
| Parameter | Value |
|---|---|
| Output type | Semiconductor relay |
| Maximum current | 15 A |
| Controlled by | IOcan power management logic |
This output allows IOcan to manage transmission power sequencing without external relays.
Analog Input Measurement¶
IOcan analog inputs use resistor dividers to allow measurement of automotive voltage ranges while protecting the internal ADC.
Two divider configurations are used.
0–12 V Analog Inputs (AN1–AN7)¶
These inputs are designed for direct connection to typical automotive signals.
Electrical characteristics:¶
| Parameter | Value |
|---|---|
| Maximum measurable voltage | 16 V |
| Typical signal range | 0–12 V |
###Typical applications:
- ignition signals
- switch inputs
- 0–12 V sensors
- digital signals from ECUs
0–5 V Analog Inputs (AN8–AN11)¶
These inputs are intended for low-voltage sensors.
Electrical characteristics:¶
| Parameter | Value |
|---|---|
| Maximum measurable voltage | 6 V |
| Typical signal range | 0–5 V |
Typical applications:¶
- throttle position sensors
- pressure sensors
- position sensors
Frequency Inputs¶
Frequency inputs share hardware with selected analog inputs.
Supported signal types:¶
- square wave signals
- hall-effect sensors
- pulse outputs from ECUs
Typical uses:¶
- engine speed
- wheel speed
- vehicle speed
Signal conditioning and scaling are configurable in software.
Sensor Power Supply¶
IOcan provides a dedicated sensor supply for analog and frequency inputs.
SENSOR5V¶
| Parameter | Value |
|---|---|
| Output voltage | 5 V |
| Maximum output current | 0.5A |
| Intended use | powering external sensors |
sGND¶
Ground reference for sensors connected to analog or frequency inputs.
Using the dedicated sensor ground improves measurement accuracy and reduces noise.
Digital Outputs¶
Digital outputs share hardware with selected analog input pins.
| Parameter | Value |
|---|---|
| Maximum current | 0.9 A per output |
| Output type | low-side driver |
##Typical applications:
- relay control
- indicator outputs
- actuator control
Outputs are fully configurable in the IOcan configuration tool.
CAN Interfaces¶
IOcan provides four independent CAN interfaces.
| Parameter | Value |
|---|---|
| Number of interfaces | 4 |
| Protocol | CAN-FD |
| Compatibility | CAN 2.0B |
Each CAN interface consists of a differential pair:
- CANxH
- CANxL
Termination can be enabled or disabled depending on network topology.
Environmental Considerations¶
IOcan is designed for automotive environments.
Proper wiring and grounding practices are required to ensure reliable operation.
Recommended practices include:
- twisted pair wiring for CAN networks
- short CAN stubs
- proper termination at both ends of the bus
- properly crimped terminals
- soldering of the wires is not recommended
- Please remember that this device controls part of powertrain. Please take great care when wiring the device and the transmission.
