Power measurement at a fieldbus station
| |
Risk of injury through electric shock and damage to the device! Bring the Bus Terminal system into a safe, voltage-free state before starting mounting, disassembly or wiring of the Bus Terminals! |
The example illustrates power measurement at three circuits of the fieldbus station. The terminal measures the:
- Power consumption of the Bus Coupler and E-bus supply
- Power consumption of the power contacts
- Power consumption AS-i over the AS-i potential feed terminal (EL9520)
Notice | |
Note rated current! In the example, the special type EL3443-0010 is used with an extended current measuring range (5 A max.). The standard EL3443 type is not suitable for this application example because the current measuring range is too small (1 A)! |
