The 07AC91 GJR5252300R0101 is a Analog I/O Unit. Extensible central unit with CS31 bus 12 isolated inputs 24 V d.c. and 8 transistor outputs 24 V d.c. / 0.5 A with 4 analog inputs and 2 analog outputs interface for programming or ASCII or MODBUS communication 24 V d.c. power supply.The 40/50 series central unit disposes of a time delay in order to save the necessary information for the next startup should there be a power drop or cut. Saving program internal data is only possible on the 40/50 series central unit which possesses an battery. 

Prior configuration of the central unit is required to save all or part of the data. If the configuration is absent then all functions and internal data will be reset to 0. The intermediate calculations of the functions used in the user program, necessary for the following cycles, are placed in variables called historic variables. It is also possible to save historic variables.
