SIL 3, 4 A, 24 Vdc Power Distribution and Diagnostic Module


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 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 / Class I, Division 2 or Class I, Zone 2.


• Installation in Zone 2 / Safe Area
• Separate single or redundant 24 Vdc Supply in groups of 4 A each into the power bus
• Supply current to approximately 40-50 D5000 modules.
• 5 LEDs indicate power presence, supply variation, supply faults, common bus faults.
• 2 replaceable 5x20, 6 A fuses.
• Very low internal dissipation (ideal diode circuits)
• Operating temperature range –40 to +70°C.
• EMC Compatibility to EN61000-6-2, EN61000-6-4, EN61326-1, EN61326-3-1 for safety system
• Simplified installation on beginning, end or both sides of Isolators package.
• Simplified installation using standard DIN-Rail and plug-in terminal blocks, with Power Bus.
