Note! Ouflex programming training is required to purchase this product
The Ouman Ouflex A presents an advanced automation system designed to efficiently monitor and manage building automation within a property. Programming the Ouflex A building automation system is seamlessly achieved using the user-friendly Ouflex Tool. A crucial component of the Ouman property automation system, the Ounet web-based SCADA, seamlessly integrates with the Ouflex A.
Mounted on a DIN-track, the Ouflex A is a versatile device for monitoring, controlling, and adjusting various parameters. With 34 I/O points and a range of telecom and bus connections, it offers flexible connectivity options. Moreover, it provides 24 V AC and 15 V DC voltage outputs. The device is equipped with a built-in Web UI accessible via LAN or the internet, enabling remote control capabilities anytime, anywhere. The display module of the device can be detached and relocated for convenience.
Expanding the number of I/O points is made possible through external I/O modules connected via bus connections. Designed to comply with DIN standards, the device can be mounted on most substation cabinet models, aided by detachable terminal blocks that simplify the installation process.
