This internal system supply module increases the capacity of the system supply by 2 A for fieldbus nodes with high current requirements (sum of the internal current consumption of the I/O modules).
If required, additional system supply modules with bus power supply can be used.
The module also supplies field-side power to the adjacent modules via the power jumper contacts.
The device is ideal for operation in extreme environments thanks to:
- An extended temperature range
- Greater immunity to impulse voltages and electromagnetic interference
- Higher vibration and shock resistance
