AVT5222 A +

Here is another design of the device intended for use in automation systems with the acquisition of many data. It is a universal digital input module with RS-485 interface. Perfect for use in systems where it is necessary to collect information from many devices placed at considerable distances from each other. The module was built based on the AVR microcontroller and equipped with a connector for programming the microcontroller in the system. The basic version has 8 galvanically isolated inputs, 1Wire, I2C, INT0, INT1 connector.

Recommendations: a universal module that can find applications in building automation, industrial systems, etc.

Basic parameters:

• eight independent, opto-isolated digital inputs with memory option.
• the device is based on the popular MAX485 system with a 12 kV receiver impedance typical for the RS485 standard.
• the device can collect information in the form of the presence or absence of 5 V ... 12 V voltage from eight sources

Includes printed circuit board, programmed layout and documentation.

A version with a set of independent components is available
