Background information:

W&T Web-IOs are often used in larger quantities at a centralized location. In such situations a common power supply for the devices makes the application much more transparent than would be the case if the devices were powered individually. If there is no 48V supply available in the installation, this task can be solved elegantly and cost-effectively using the model 11089 40W DIN rail mount power supply, which can be used to power multiple 48V devices from a central location. The power supply can of course also be used where in addition to the 48V supply for the Web-IO component group power is also needed for supplying the rest of the installation. In this case you only need to ensure that the overall power requirements do not exceed the current capacity of the DIN rail power supply.
