The MINI and MIX series of I/O modules with RS485 and IP (2 Ethernet) have been designed for building distributed control systems using MAC36, AAC20, or another controller. Each module is equipped with the most commonly used types of I/O in building automation. Depending on the version, the device has 18 or 38 inputs and outputs, a mix of all types of I/O in one unit. All I/O modules have BTL and UL certificates.
The modules with RS485 and IP (2 Ethernet) are factory-equipped with the two most popular open communication protocols: Modbus (ASCII, RTU, TCP/IP) and BACnet (MS/TP, IP), which are selected using DIP switches. Rotary switches are used to set the module address, which facilitates and accelerates the process of commissioning the system. Built-in mini USB allows for the initial configuration of the unit without external power supply.
Built-in Modbus gateway TCP/IP to Modbus ASCII/RTU enables to connect additional modules/devices that communicate via Modbus RS485.
Thanks to supporting open communication standards I/O modules can be installed in both new and completed installations, as part of existing BMS. This versatile device will fit any BMS perfectly.
This user manual outlines all information specific to using I/O modules in the BACnet protocol.
