1606-XLERED20 —Redundancy Module
The 1606-XLERED20 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 rated for 20 A for ambient temperatures up to 70 °C (158 °F) and are
individually decoupled by utilizing MOSFET technology. The inputs can also
be operated up to 24 A when the ambient temperature does not exceed 45 °C
(113 °F).
The output can be loaded with nominal 20 A at 70 °C (158 °F) or 24 A at 45 °C (113
°F) continuous current.
Using MOSFETSs instead of diodes reduces heat generation, losses and
voltage drop between input and output. Due to these advantages, the unit is
narrow and only requires 32 mm (1.26 in.) width on the DIN rail.
The device does not require an additional auxiliary voltage and is self-powered
even if there is a short circuit across the output.
1606-XLERED20Y—Redundancy Module with Automated Load
The 1606-XLERED20Y is a dual redundancy module, which can be used to
build 1+1 redundant systems.
The device is equipped with two input channels, each rated for 10 A for
ambient temperatures up to 70 °C (158 °F) and are individually decoupled by
utilizing MOSFET technology. The inputs can also be operated up to 12 A when
the ambient temperature does not exceed 45 °C (113 °F).
The output can be loaded with nominal 20 A at 70 °C (158 °F) or 24 A at 45 °C (113
°F) continuous current.
Using MOSFETSs instead of diodes reduces heat generation, losses and
voltage drop between input and output. Due to these advantages, the unit is
narrow and only requires 32 mm (1.26 in.) width on the DIN rail.
The device does not require an additional auxiliary voltage and is self-powered
even if there is 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 if the output
current is too high, which could prevent redundancy if one power supply fails.
The signal also reports too low or too high input voltages.
1606-XLSBUFFER24—Buffer Module
The 1606-XLSBUFFER24 buffer module is a supplementary device for DC 24V
power supplies. It delivers power to bridge typical mains failures or extends
the hold-up time after the AC power is turned off.
