UPS module is available in four variations:

The UPS module is used for the uninterruptible power supply of CX CPUs and any connected CX components. In the event of a failure of the external supply, the module ensures that the application software can save important data, e. g. on a Compact Flash card, NOVRAM or in a database via the network. During the UPS retention time, the machine or process can be transferred into a defined state, and the operating system can be shut down. The retention time can be set via a rotary switch or via software.

The use of state of the art capacitors makes this UPS module – unlike other battery powered techniques – absolutely maintenance-free and offers rapid charging. The module can simply added to a CX system. Only a 24 V DC supply cable is needed. The 24 V DC output voltage of the UPS is protected against short circuit and overload. The CX1100-09xx may be retrofitted on site. A DPRAM user interface provides options for settings and UPS status messages.

The functionality of the UPS is therefore independent of the operating system to be used. No driver software is required. The TwinCAT System Manager recognizes the UPS module automatically, and the UPS signals are available to the PLC programmer. A controlled 24 V DC power supply unit with a minimum output current of 4 A is required.
