BACnet MS/TP IO-Module 2DI/2RI/3AO/2DO

BACnet MS/TP IO-Module 2DI/2RI/3AO/2DO

BAC-IO9 and BAC-IO9-AI have been designed to be a compact wall mounted BACnet MS/TP input and output modules.

The module has 2 volt-free digital inputs for measurements e.g. for windows, occupancy sensors and so on. The module has 2 digital outputs, 24Vac triacs switching the plant items on/off. The IO9 modules has 2 inputs for measuring NTC10 temperature, resistive measurements (e.g. light level) or volt-free on/off signals.

The IO9-AI models have 2 inputs for measuring 0..10Vdc signals. The three analogue 0..10Vdc outputs complete the compact IO-modules. With the analogue outputs it is possible to control zone valves and other modulating plant equipment.

The modules support BACnet MS/TP communications with most commonly used baud rates and parity settings. The module also supports BACnet device and object discovery allowing fast and efficient programming.
