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.

al45d

For 4–20 mA current loops, SIL 2 / SIL 3

• Low-noise linear version or high-density switching version

• Total protection

Short circuits, overloads, thermal protection

• 1 to 8 isolated outputs

Complete circuit independence

• Extended-temperature, long-life version:
AL45DLL “long life” with polymer-filled

• Applications

4–20 mA loop power supply
with current limiting (transmitter protection)
Hart protocol, very low noise

• SIL2 and SIL3 compliance according to IEC 61508 (redundant version)
These power supplies are available with 1 to 8 outputs and are particularly well-suited for implementing 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 the use of a single high-power output 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.
Description:
– The switching version offers high power density
without overheating due to its high efficiency; it also accommodates
a wide range of input voltages (AC or DC)

al25

• Universal input: 20–265 V AC/DC

• Full protection: short circuits, overloads, thermal protection

• 1 to 3 isolated outputs (1 watt per output)

3.3 V to 24 V up to 72 V via coupling
: 30 mA to 500 mA depending on the output voltage

• Very compact size: 62 x 63 x 23 mm

• 4–20 mA loop power supply applications, instrumentation

The standard version of the AL25 is designed to provide a separate power supply for 4–20 mA current loops.
It is a very compact and fully protected unit, available with 1 to 3 isolated outputs that are current-limited to
protect sensors in the event of a loop fault.
This power supply can be customized for any other single or symmetrical output voltage.
