1. GENERAL DESCRIPTION

The YR2.DIODE is a decoupling module, which can be used for various purposes. The most popular application is to configure a highly reliable and true redundant power supply systems.

Another interesting application is the separation of sensitive loads from non-sensitive loads. This avoids the distortion of the power quality for the sensitive loads which can cause controller failures.

The YR2.DIODE is the perfect solution to use in a redundant system, if the power supply itself is equipped with a DC-OK signal (e.g.: DIMENSION QSeries).

Alongside with the YR2.DIODE, there exists the YRM2.DIODE which has a monitoring circuitry included. LEDs and relay contacts signal when one of the two DC-input voltages is not in range due to a non-functioning power supply.

Unique quick-connect spring-clamp terminals allow a safe and fast installation and a large international approval package for a variety of applications makes this unit suitable for nearly every situation.

INTENDED USE

The decoupling module shall only be installed and put into operation by qualified personnel. This decoupling module is designed for installation in an enclosure and is intended for the general use, such as in

industrial control, office, communication, and instrumentation equipment. Do not use this device in aircraft, trains and nuclear equipment, where malfunctioning of the power supply may cause severe personal injury or threaten human life.

TERMINOLOGY AND ABREVIATIONS

PE and symbol PE is the abbreviation for Protective Earth and has the same meaning as the symbol .

Earth, Ground This document uses the term “earth” which is the same as the U.S. term “ground”.

T.b.d. To be defined, value or description will follow later.

DC 24V A figure displayed with the AC or DC before the value represents a nominal voltage with

standard tolerances (usually ±20%) included. E.g.: DC 12V describes a 12V battery disregarding whether it is full (13.7V) or flat (10V)

24Vac A figure with the unit (Vac) at the end is a momentary figure without any additional

tolerances included.

The Lifetime expectancy shown in the table indicates the operating hours (service life) and is determined by the lifetime expectancy of the built-in electrolytic capacitors.

Lifetime expectancy is specified in operational hours. Lifetime expectancy is calculated according to the capacitor’s manufacturer specification. The prediction model allows a calculation of up to 15 years from date of shipment.

MTBF stands for Mean Time Between Failure, which is calculated according to statistical device failures, and indicates reliability of a device. It is the statistical representation of the likelihood of the unit to fail and does not necessarily represent the life of a product.
