ABB DSDX452

The ABB DSDX452 module is an input/output module, also known as a control module, which is used to output signals or provide a switching signal when there is a control requirement to make the controlled device act. At the same time, it can also receive feedback signals from the device to report to the host 1. DSDX452 module is an important part of the fire alarm linkage system. Through the output module, the external control equipment that needs to be linked, such as smoke exhaust valve, air supply valve, fire shutter door, fan, alarm bell, etc., can accept the action of the equipment.
