21.3. YRM2.DIODE - REDUNDANCY MODULE
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 outpu
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 22.6 for wiring information.
21.4. UF20.481 - BUFFER MODULE
The UF20.481 buffer module is a supplementary device for 48V DC/DC converters. It delivers
power to bridge typical supply voltage faults or extends the hold-up time after turn-off of
the input pow
In times when the DC/DC converter provides sufficient voltages, the buffer module stores
energy in integrated electrolytic capacitors. In case of a supply voltage fault, this energy is
released again in a regulated process.
The buffer module does not require any control wiring. It can be added in parallel to the load
circuit at any given point.
One buffer module can deliver 20A additional current. Buffer modules can be added in
parallel to increase the output ampacity or the hold-up time.
