The IoTextra Input is an 8-channel digital input module. The maximum input level for a digital signal is 36 VDC. All channels have individual galvanic isolation with an electrical strength of 3750VRMS and TVS input protection.
This module is a member of the loTextra 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:
The module provides an indication of the digital input channel status.
There are two modes for using the IoTextra Input module:
· GPIO Mode. In this mode, the input signal states are read using the AP0-AP7 signals on the HOST-P connector.
· I2C Mode. In this mode, the input signal states are read via the I2C bus using the I/O expander installed on the module (TCA9534 or a compatible one). Up to 16 modules can be connected to one I2C bus
It is also possible to use the AP0-AP7 signals for some channels via the HOST-P connector and for the rest via the I/O expander.
Module power supply is 5VDC, which feeds a 3V3 regulator for powering the logic section. Protection against reverse power supply polarity is included.
Transient suppression and electrostatic discharge protection of signals on Qwiic© connectors is provided by a TVS diode assembly (ESD protection).
Compatible with Raspberry Pi, Raspberry PICO, Arduino Nano, Adafruit Feather, Teensy, ESP32, SeeedStudio XIAO, Nucleo, and others.
Module size: 47 x 56 mm. The module has mounting holes for installation in the base module or a Raspberry Pi. The IoTextra Input can be used with IoTsmart or IoTbase modules.
