SIL3 24 Vdc 4 A Power Distribution with Diagnostics

The D5202 is used to protect the power system by limiting the maximum supply current for a set of D5000 modules connected via Power Bus. This is particularly useful when the source Power supply provides currents that are higher than the ones required from the modules. It is also capable of repeating the common fault signal from the Power Bus via a SPDT relay. For single power supply, 3 LEDs are present to monitor line presence, supply fault (supply voltage out of 25% variation), common bus fault and a replaceable 5x20, 6 A fuse. For redundant power supply, 5 LEDs are present to monitor line presence, supply fault (supply voltage out of 25% variation for each supply source), common bus fault and 2 replaceable 5x20, 6 A fuses. 2 SPDT relay contacts provide remote alarming for the above mentioned failures. In case of fault of one supply source the D5202S exchanges to the working one using a circuit (ideal diodes) with just a few mW dissipation, thus increasing reliability and greatly reducing internal power dissipation.
