21.3. YRM2.DIODE - REDUNDANCY MODULES
The YRM2.DIODE is a dual redundancy module, which can be used to build 1+1 or N+1
redundant systems.
The device is equipped with two input channels each 10A nominal, which are individually
decoupled by utilizing diode technology. The output can be loaded with nominal 20A.
The device does not require an additional auxiliary voltage and is self-powered even in case
of a short circuit across the output.
The device has a monitoring circuit included and is the perfect choice when the power supply
has no DC-OK function. Two LEDs and two relay contacts signal when one of the two input
voltages is not in range due to a non-functioning or disconnected power supply.
The unit is very slender and only requires 32mm width on the DIN rail.
See chapter 22.5 for wiring information.
21.4. YR20.246 - REDUNDANCY MODULE
The YR20.246 is a dual redundancy module, which can be used to build 1+1 redundant
systems.
The device is equipped with two input channels each 10A nominal, which are individually
decoupled by utilizing MOSFET technology. The output can be loaded with nominal 20A.
Using MOSFETSs instead of diodes reduces heat generation, losses and voltage drop between
input and output. Due to these advantages, the unit is very slender and only requires 32mm
width on the DIN rail.
The device does not require an additional auxiliary voltage and is self-powered even in case
of a short circuit across the output.
The device is equipped with an automated load sharing feature, which balances the load
current between the two input channels. It also monitors the function of the redundancy circuitry and provides a
signal in case of too high of output current, which could prevent redundancy, if one power supply fails. The signal also
reports too low or too high input voltages.
See chapter 22.5 for wiring information.
