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 the internal power consumption of all modules is higher than 2 A, an additional supply module must be added.
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:
- Extended temperature range
- Greater immunity to impulse voltages and electromagnetic interference
- Higher vibration and shock resistance
