DESCRIPTION

IoTextra Octal2

8-channel digital I/O module · 4 isolated inputs · 4 outputs · galvanic isolation · GPIO and/or I²C modes

Bipolar and Extended signal modes · HOST and Qwiic connectors · 47×56 mm · 5 VDC supply

Part of the IoTextra series · compatible with IoTsmart and IoTbase · Open Hardware

This module is a member of the IoTextra series, which serves as a fundamental building block of our ecosystem and embodies the Make Things Happy Philosophy. It is engineered to bridge the gap between rapid prototyping and industrial-grade reliability.

Hardware Synergy: The module is compatible with both IoTsmart and IoTbase series.

Software Power: This hardware compatibility unlocks the full potential of the IoTflow platform. It enables you to:

  • Create custom Node-RED nodes effortlessly.
  • Integrate via MQTT with third-party global platforms like Blynk.
  • Scale your project from a single node to a complex industrial network.

Key Specifications

  • Configuration: 4 digital inputs, 4 NPN digital outputs
  • Isolation: individual galvanic isolation per channel, 3750Vrms dielectric strength
  • Digital inputs: up to 36VDC; logic thresholds 0–2V (logical "1"), 4–36V (logical "0"); selectable bipolar or unipolar input mode
  • Digital outputs: NPN Darlington power transistors, up to 8A (16A peak) at up to 100VDC, 20W max dissipation
  • GPIO Mode: inputs/outputs controlled via AP0–AP7 signals on the HOST-P connector
  • I²C Mode: controlled via I²C using the onboard I/O expander (TCA9534 or compatible); up to 16 modules on one bus
  • Hybrid control: some channels via HOST-P GPIO, others via the I²C expander, simultaneously
  • Connectors: HOST-P10 or HOST-P12, Qwiic × 2, PWR
  • Status indication: per-channel digital I/O status LEDs
  • Size: 47 × 56 mm, with mounting holes for base-module or Raspberry Pi installation

Operation Modes

🔌 Standalone
Input states and output control are available through the HOST-P10/P12 connector, or via the I²C bus using the onboard I/O expander.
🧠 Smart
An IoTsmart module is inserted vertically into HOST-P12. I/O control and the 5V module supply are both provided through HOST-P12, powered from the IoTsmart module.
🏗 Mezzanine
The module is installed into an IoTbase carrier board. I/O control and the 5V module supply are provided through HOST-P12.

Applications

🏭 Industrial Automation (PLC / Data Acquisition)
Digital inputs read limit switches, proximity sensors, and process interlocks; transistor outputs drive pilot lamps, small solenoids, and contactor coils.
🔔 IIoT (Machine Status Monitoring)
Digital inputs monitor e-stops, door switches, and machine status contacts; transistor outputs drive local status panels and indicator lamps.
🤖 Robotics & Lab Automation
Inputs read encoder pulses, limit switches, and test-rig trigger signals; outputs drive small motor drivers, solenoids, and valves in automated test benches.
🏠 Smart Home
Inputs connect to door/window contacts and motion sensors; transistor outputs drive buzzers, LED indicators, and low-voltage actuators.
