BACnet MS/TP IO-Module 2DI/2DO

BACnet MS/TP IO-Module 2DI/2DO

BAC-DIO4 has been designed to be a compact wall mounted BACnet MS/TP input and output module. The module has 2 volt-free digital inputs for measurements e.g. for windows, occupancy sensors and so on. The module has also 2 digital outputs, 24Vac triacs switching the plant items on/off. The module supports 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.
