Barix X8

Barix X8 - TTL I/O RS-485 Modbus/RTU Module for Automation, AV, and Monitoring

Barix X8 is a compact and versatile I/O module designed for AV control systems, building automation, and remote infrastructure monitoring. It features eight independent TTL-level digital input/output channels, each configurable and equipped with programmable pull-up resistors. Each input can support a Dallas 1-Wire temperature sensor, enabling localized environmental data collection.

Communication with host systems is handled via a 2-wire RS-485 interface with Modbus/RTU protocol support, making the X8 an ideal Modbus I/O converter for integration into commercial control networks. Additionally, the module supports Wiegand interface functionality using two of its I/O channels.
