alr20 al100

• Linear or pulse-width modulation (PWM) version
• Full protection: short circuits, overloads, thermal

• 1 to 8 isolated outputs AL100
• 1 to 4 isolated outputs ALR20
• Compact design

• Applications
, 4–20 mA loop power supply
, instrumentation, sensors, etc.

These power supplies are available with 1 to 8 outputs and are particularly well-suited for use with converters in a two-wire technical
(powered by the 4–20 mA loop). The isolation between each output eliminates ground-loop
s that could affect the measurement. Since each output is independent and low-power, any risk of equipment damage is eliminated compared to using a single-output high-power supply. The independence of each loop significantly increases the reliability of the installation. The outputs allow for all wiring combinations to adapt to specific needs; connecting them in series or parallel enables the creation of a balanced output, increasing the output current or voltage.

al71-bus

• Direct power supply via the bus for 8 CML36 modules
– No wiring required; 24V distributed directly over the communication bus
– Ensures complete bus isolation
– Allows direct 230Vac power supply
– Low-noise linear power supply
– 24V 250mA output

– 24V auxiliary output terminal block

This power supply is particularly well-suited for use with CML36 data acquisition systems.
The output’s very high isolation impedance eliminates ground loop issues and ground currents
that can affect measurements or, in extreme cases, damage the modules. This solution significantly improves the reliability of
the installation and facilitates the implementation of CML36 modules. It helps ensure compliance with the implementation recommendations
for silo thermometry data acquisition systems.
