General Description:
The D5202S is used to protect the power system by limiting the maximum supply current for a set of D5000 modules connected via Power Bus.
This module is suitable for applications requiring SIL 3 level (according to IEC 61508:2010 Ed.2) in safety related systems for high risk industries.
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.
Mounting on standard DIN-Rail, with Power Bus, in Safe Area / Non Hazardous Location or in Zone 2.
Functional Safety Management Certification:
