The YRM2.DIODE 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 10 A output current and one output, which can carry nominal currents up to 20 A. The module is suitable for power supplies with constant current overload behavior as well as any kind of "Hiccup" overload behavior. The YRM2.DIODE has a monitoring circuit included and is the perfect solution when the power supply has no DC-OK function. Two LEDs and two relay contacts signal when one of the two DC input voltages is not in range due to a nonfunctioning or disconnected power supply. In addition to the YRM2.DIODE is the YR2.DIODE which has no monitoring circuitry included. This is the perfect fit when the power supply itself is already equipped with a DC-OK signal (e.g.: Dimension Q series). Large screw terminals allow an easy installation and a huge international approval package for a variety of applications makes this unit suitable for nearly every situation.
