5SHY4045L0006 3BHB030310R0001 IGCT module

The standard motherboard is designed for 8 or 16KF modules Power feed and system connector to DCS are integrated in the motherboard, which results in noticeable space savings in the interface cabinet. The power source has a redundant design, increasing the reliability of the system. The operating status of the power supply is monitored and reported via led and relay output. The KF modules are interfaced to the motherboard himself by using 2- to 6- pin coded cable connectors.(FSY...) The motherboard configuration is mounted on a stable metal plate. There are two brackets, on the back for mounting the board quickly and easily to a standard DIN rail in accordance with DIN EN 50022 or similar.

The ISOMETER® of the IRDH275 series is designed to monitor the insulation resistance of unearthed main circuits (IT systems) AC, AC/DC 0…793 V resp. DC 0…650 V. The AMPPlus measurement method meets the particular requirements of modern power supplies which often include rectifiers, converters, thyristor-controlled DC drives and directly connected DC components. In these systems often high leakage capacitances against earth occur due to interference suppression measures. The IRDH275 automatically adapts itself to the existing system conditions. In combination with a coupling device, the devices can also be used for higher voltages. An external supply voltage allows de-energised systems to be monitored too. For door mounting into distribution panels, refer to type IRDH375(B).

When the insulation resistance between the system conductors and earth falls below the set response value, the alarm relays switch and the alarm LEDs light up. Two separately adjustable alarm relays allow to distinguish between prewarning and alarm. The measured value is indicated on the LC display or an externally connectable measuring instrument. In this way any changes, for example when circuits are connected to the system, can be recognised easily. The fault message can be stored. The fault memory can be reset by pressing the reset button. By pressing the test button, the function of the device as well as the connections to system and earth can be tested. Pressing the Info button provides additional information, such as the existing system leakage capacitance or device settings. The function of the device and the system and earth connections are continuously monitored. When a fault occurs, the system fault relay switches and the alarm LED “system fault” lights up. The parameterisation of the device can be carried out via the LC display or the function buttons integrated in the front plate.
