The CX2100-0004 power supply module is used for supplying power to the components (CPU modules, system and extension modules) of a CX2033 system. The power supply module is controlled via TwinCAT. An FSTN LC display with 2 x 16 characters and a selector switch as well as an enter key allow the querying of internal status values as well as self-created display parameters or menus with and without input options. EtherCAT or Bus Terminals can be connected on the right-hand side – the respective bus system is detected automatically and operated by the CPU. Power is supplied to the E-bus or K-bus electronics in the I/O terminals by an integrated, but internally separate power supply unit with 2 A at 5 V DC. The CX2100-0004 is in principle passively cooled, has no fan and is intended for operation in the extended temperature range from -25 to +60°C. The standard power supply CX2100-0004 provides a maximum output of 45 W.
