5.2.8 Connecting SIM4F sensor signals
In RIO600, SIM4F accepts three phase current signals to RJ-45 connectors.
The input signals are fed from a current sensor based on the Rogowski coil principle.
The sensor should be equipped with an RJ-45 connector for connection with the
SIM4F module. There are current sensors which are wired to a single RJ-45 connector
with adapter.
• Use the cable connector type RJ-45 for connecting the sensors with SIM4F.
• Connect current signals to the sensor input for proper operation.
Preferred ABB current sensor is KECA 80 C85.
RIO600 supports also split-core current sensor type for retro-fit purposes. Preferred
split-core sensor is KECA 80 D85.
