IoTextra Input - Isolated 8 DI channels module

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 3750V_RMS and TVS input protection.

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.
