IO Module

Description

The IO Module provides six individually configurable ports, each one has multimeter capabilities.

The key features are:
Software

• Programmable via the Module RESTful API
  • Simple programming example (Python)
• Official openHAB plugin
• Bootloader & Firmware update support.
  • Source code on Github

Hardware

• 6 individually configurable ports.
• Each port supports the following functions:
  • Analog Input
  • Digital Input with frequency counter
  • Current measurement (output)
• Each port can be configured via software as 5V or 12V output.
• All ports are protected against voltages up to 50V (see below).
• Up to 5W output power per port.
• Active overload protection
  • Includes voltage, current and power monitoring.
  • Configurable voltage and power limits.
  • Typical reaction time <5ms.
  • Notification support, error triggers software notification for the application.
• Failsafe design
  • In case of power failure or software problem, the ports are automatically disconnected via relay.
  • Each port has physical fuses for extreme cases.
• Continuous monitoring of voltage, current and power with 1000 samples per second/port.
• Good ESD and surge protection allows direct control of inductive loads.
• Operating temperature (ambient air) range 0°C – 50°C.
• Storage temperature range -40°C – 85°C.

Applications

• Relay control
• Fan control
• Motor control (PWM)
• Electronic door lock control
• Door/Window open/closed detection
• LED control
• Analog sensor reading (temperature, humidity, photodetector… )

Hardware Specification

Output

* In output mode it depends heavily on the resistance of the interference source
Port is turned off if over-voltage is detected  
** Depends on the load
*** Use as a current sink possible, however, without overcurrent detection

Input

Digital input

Important notes

• The maximum output power may be limited by the power supply (power module).
• The connections/modules are not galvanically isolated.
