GENERAL DESCRIPTION

The YR2.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 10A output

current and one output, which can carry nominal

currents up to 20A. The module is suitable for power

supplies with constant current overload behavior as well

as any kind of “Hiccup” overload behavior.

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 Q-Series). In

addition to the YR2.DIODE is 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.

Another interesting application for this diode module is

to separate sensitive loads from non-sensitive loads. This

avoids the distortion of the power quality for the

sensitive loads which can cause controller failures.

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.

YR2.DIODE DC12-48V (120V), 20A, DUAL REDUNDANCY MODULE Y-Series 1. INTENDED USE This redundancy 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. This redundancy module can be used with any type of power supply as long as the maximum ratings are not exceeded. It is suitable for power supplies with constant current overload behavior as well as any kind of “Hiccup” overload behavior.

Each control circuit, auxiliary voltage source, or other circuitry in the module are designed separately for each input. The dual input redundancy module can be considered as two single redundancy modules combined together in one housing.

PHYSICAL DIMENSIONS AND WEIGHT Weight DIN-Rail Installation clearances 290g / 0.64lb Use 35mm DIN-rails according to EN 60715 or EN 50022 with a height of 7.5 or 15mm. The DIN-rail height must be added to the unit depth (102mm) to calculate the total required installation depth. See chapter 2 Fig. 15-1 Front view Fig. 15-2 Side view Apr. 2014 / Rev. 1.4 DS-YR2.

RECOMMENDATIONS FOR REDUNDANCY Recommendations for the configuration of redundant power systems: • Use separate input fuses for each power supply. • Use three-phase power supplies to gain functional safety if one phase fails. • When single-phase power supplies are utilized connect them to different phases or mains circuits if possible.

YR2.DIODE DC12-48V (120V), 20A, DUAL REDUNDANCY MODULE Y-Series 17.6. EXAMPLE: REDUNDANCY FOR CONTROLS The example shows a cost effective solution to get redundant power for a PLC or controller system. In many cases, two power supplies are used; one for the demanding loads and another one for the controls and sensitive loads. The power supply for the demanding loads can be used as a redundant source to supply the controls.
