Product information "IKI-55 M"
The IKI-55 Feeder Control Unit can be used in load switchgear for directional fault detection, load flow measurement, and control of load and ground switches. Likewise, a number of automation and monitoring functions are available with the IKI-55.
The IKI-55 is network-capable in its basic version and can communicate with the control station and other remote stations via various communication protocols. It can also be used as a Modbus master. The IKI-55 M is a Modbus-only variant.
The IKI-55 is designed for the connection of small-signal current transformers according to IEC 61869-10 as well as small-signal voltage transformers according to IEC 61869-11. In conjunction with a sensor adapter, conventional conversion transformers for current measurement as well as capacitive and precision dividers can be connected.
