GENERAL DESCRIPTION
The MLY10.241 is a simple 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 5A
output current and one output, which can carry
nominal currents up to 10A. The module is suitable for
power supplies with constant current overload behavior
as well as any kind of “Hiccup” overload behavior.
Large screw 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.

shall A key word indicating a mandatory requirement

1+1 Redundancy Use of two identical power supplies in parallel to provide continued operation following most
failures in a single power supply. The two
power supply outputs should be isolated
from each other by utilizing diodes or
other switching arrangements.
E.g. two 2.5A power supplies are needed to
achieve a 2.5A redundant system.
N+1 Redundancy Use of three or more identical power
supplies in parallel to provide continued
operation following most failures in a
single power supply. All power supply
outputs should be isolated from each other
by utilizing diodes or other switching
arrangements. E.g.: To achieve a 10A redundant system, five 2.5A power supplies are needed in
a N+1 redundant system.

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.
Do not use this redundancy module in equipment, where malfunction may cause severe personal injury or threaten
human life.
This device is designed for use in hazardous, non-hazardous, ordinary or unclassified locations.
2. INSTALLATION REQUIREMENTS
This device may only be installed and put into operation by qualified personnel.
This device does not contain serviceable parts.
If damage or malfunction should occur during installation or operation, immediately turn power off and send unit to
the factory for inspection.
Mount the unit on a DIN-rail so that the input terminals are located on the top and the output terminals on the
bottom of the unit. For other mounting orientations see de-rating requirements of chapter 16.6. in this document.
This device is designed for convection cooling and does not require an external fan. Do not obstruct airflow and do
not cover the ventilation grid (e.g. cable conduits) by more than 30%!
Keep the following installation clearances:
40mm on top,
20mm on the bottom,
5mm on the left and right sides are recommended when the device is loaded permanently with more than 50% of the
rated output current. Increase the side clearance to 15mm in case the adjacent device is a heat source (e.g. another
power supply).
WARNING
- Turn power off before working on the device. Protect against inadvertent re-powering.
- Make sure that the wiring is correct by following all local and national codes.
- Do not open, modify or repair the unit.
- Use caution to prevent any foreign objects from entering the housing.
- Do not use in wet locations or in areas where moisture or condensation can be expected.
- Do not touch during power-on, and immediately after power-off. Hot surfaces may cause burns.
Notes for use in hazardous location areas:
The redundancy module is suitable for use in Class I Division 2 Groups A, B, C, D locations and for use in Group II
Category 3 (Zone 2) environments and is evaluated according to EN 60079-0:2009 and EN 60079-15:2010.
WARNING EXPLOSION HAZARDS!
Substitution of components may impair suitability for this environment. Do not disconnect the unit unless power has
been switched off or the area is known to be non-hazardous.
A suitable enclosure must be provided for the end product which has a minimum protection of IP54 and fulfils the
requirements of the EN 60079-15:2010.
Risk of electrical shock, fire, personal injury or death.

5. LIFETIME EXPECTANCY AND MTBF
The redundancy module has two input channels which are completely independent from each other. 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. The only
common point is the circuit trace that ties the two separate circuits together at the output.
The MTBF figures below are for the entire dual input module. If the MTBF number of only one path is needed, simply
double the value from the table.
The redundancy module does not have electrolytic capacitors included. Therefore, the lifetime expectancy is extremely
high.

*) The Lifetime expectancy shown in the table indicates the minimum operating hours (service life).
**) 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 a unit to fail and does not necessarily represent the life of a product.
The MTBF figure is a statistical representation of the likelihood of a device to fail. A MTBF figure of e.g. 1 000 000h means that
statistically one unit will fail every 100 hours if 10 000 units are installed in the field. However, it can not be determined if the failed unit
has been running for 50 000h or only for 100h.

Weight 140g / 0.31lb
DIN-Rail 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 (91mm) to calculate the total required
installation depth.
Installation clearances See chapter 2

16. APPLICATION NOTES
16.1. 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.
• Set the power supply in “Parallel-Use” mode if this feature is available
• It is desirable to set the output voltages of all power supplies to the same value.
16.2. INDUCTIVE AND CAPACITIVE LOADS
The unit is designed to supply any kind of loads, including unlimited capacitive and inductive loads.
16.3. EXAMPLE: 1+1 REDUNDANCY
1+1 Redundancy up to 2.5A requires two ML60.241 power supplies (each 2.5A output current) and one MLY10.241
redundancy module.
Note: Use separate mains systems for each power supply whenever it is possible

redundancy modules.
Note: Use separate mains systems for each power supply whenever it is possible

16.5. EXAMPLE: BATTERY BACK-UP
A battery back-up requires one power supply and one MLY10.241 redundancy module.
Please note:
Set output voltage of power supply to 26.5Vdc minimum to ensure, that the load current is delivered from the power
supply and not from charger (battery). Use a fuse between battery and MLY10.241!
