15/100
3.2 Hardware
The temperature recording controller is housed in a plastic casing for DIN rail mounting. Up to 99 case
controllers can be used within the E*LDS system. As required, a BT 300 x Operator Interface and up to 4 BT 30
Temperature Displays can be connected. For a firmware update, the controller can be connected to a laptop or
PC via the USB interface. The application range of the temperature recording controller is described in more
detail in chapter
. The following diagram illustrates the system architecture of the UA 410 L AC
temperature recording controller (complete):
