As a standard configuration the device includes the CPU module (which consists of the CPU, a number of inputs and outputs, and the power supply) as well as one separate current measurement module and one module that combines three voltage measurement channels and four digital input channels.
Page 398 A A Q Q -F213 -F213 7 Construction and installation Instruction manual Version: 2.14 When an I/O module is inserted into the device, the module location affects the naming of the I/O.
