ISOLATION
AMPLIFIER
for mA / V Signals with
2-wire Transmitter Supply
MAIN FEATURES
DA561
DA561 is specially designed for signal isola-
tion and load amplification in the process in-
dustry.
A 2-wire transmitter can be connected to and
supplied from the isolation amplifier.
DA561 maintains a high isolation level (1,5 kV)
between input and output.
Current and voltage can be chosen indepen-
dently as input and output signals.
Applications
- Voltage feed for a 2-wire transmitter, and galvanic isolation from
its mA circuits.
- Galvanic isolation, when a mA signal is connected, to more than
one measurement or monitoring system.
- Conversion of measurement range 0-20 mA to 4-20 mA or vice
versa.
- Load amplification and isolation when extra high load capacity
is needed.
2-wire transmitter supply
A 2-wire, 4-20 mA, transmitter can be connected directly to the
input of the DA561, thanks to the built-in transmitter supply.
Configuration flexibility
DA561 is designed for the most usual input and output process
signals, such as mA and V.
Input and output ranges are changed with the help of jumper
connections, and a simple instruction table.
Fine adjustment of the amplifiers zero point and span can be
made with potentiometers accessible from the front of the unit.
Noise immunity
DA561 meets the high demands from the process industry of good
EMC performance. Criterion A applies for all EMC tests, which
means that the amplifier stays within specifications during EMC
influence.
Test connections
The mA output signal can be measured on the front terminals
with a low-ohm mA instrument without breaking the output
circuit.
Plug-in, screw terminals
DA561 is connected via plug-in screw terminals. The terminal blocks
and cables are easy to disconnect from the unit for convenient
dismantling and service. Installation is simplified by connection
diagrams on the front panel.
Compact mounting on DIN-rail
DA561 snaps on to a 35 mm DIN-rail and can be mounted with
high density.
