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:

CAN Gateway Pinout

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.
