IB 200 relay – Current monitoring


This current sensor feeds a 2 changeover relay contacts for a measured current from 16 A to 24 A. A potentiometer allows the setting of the relay pick up from 15 A to 25 A. The maximal admissible current of the shunt is 50 A, other versions are available.
An 110 VDC auxiliary power supply is needed for the measure and the relay command.
The electronic device is put in a B box and worked with an external shunt (P929670). The reference socket for the B box module is:EA103BFD. The devices are mounted on 35 mm rail conform to EN 50022.


The IB 200 relay is designed for current level sensing and used for example to monitor if the train magnetic brakes are active.
