PIRD20.241 Puls Redundancy Modules

YRM2.DIODE

Puls

PULS YRM2.DIODE is a redundancy unit belonging to the Y-series, designed with diode technology and ATEX approval for enhanced safety in potentially explosive atmospheres. This dual-input redundancy module supports 2 x inputs and 1 x output, operating within a supply voltage range of 18Vdc-60Vdc, including nominal values of 24Vdc, 48Vdc, and 60Vdc. It features screw-clamp connections for secure installation and is designed for DIN rail mounting, ensuring compatibility with standard industrial setups. The unit is capable of handling a rated current of 20A at 48Vdc, with a derating to 0.5A in temperatures ranging from +60°C to +70°C. It can withstand ambient air temperatures for operation between -40°C and +70°C. The YRM2.DIODE measures 32mm in width, 124mm in height, and 117mm in depth, with a peak inrush current consumption of 150A at 18-60Vdc input. It includes protection functions against short-circuits, with a 25A threshold at 6V, and supports both series/parallel operation for 1+1 redundancy and N+1 redundancy, ensuring continuous operation by using multiple power supplies in parallel. The output voltage range is 24-48Vdc, with nominal values of 24Vdc and 48Vdc. Power dissipation/losses are rated at 8.8W for 18-60Vdc input with 2x5A input and 9.5W for a 10A input. The electrical durability of the unit is estimated at 25 years or 219,000 hours at both 40°C with a 20A output and 25°C with a 10A output. Lastly, the ripple is specified at 780mVpp over a frequency range of 20Hz to 20MHz at 50Ω.
