Product Details

PIANO Series Diode Redundancy Module

The PIRD20.241 is a redundancy module, which can be used to build 1+1 and N+1 redundant systems. It is equipped with two input channels, which can be connected to power supplies with up to 10A output current and two outputs, which can carry nominal currents up to 20A. The module is suitable for power supplies with constant current overload behaviour and any kind of “hiccup” overload behaviour.
The PIRD20.241 is the perfect solution to use in a redundant system, if the power supply itself is equipped with a DC-OK signal.

Features and Benefits

• Cost effective • Dual input and output
• Two diodes (common cathode)
• DC 12-28 V ±25% wide range input
• Full power between -40°C and +55°C
• Large screw terminals

Product Application Information

Ideal for use in redundant systems and for separating sensitive loads from non-sensitive loads.
