HOW TO DISMANTLE SYSTEM 2200

16
Picture 1:
The back panel of the module is
detached from the housing by way
of a screw-driver.
Picture 2:
After this, the back panel can be
pulled out together with the PCB,
but please notice the position of the
PCB as there is a number of diffe-
rent positions in the house. Do not
pull the wires unnecessarily, instead
pull the PCB.
Switches and jumpers can now be
moved.
When assembling the back plate
and housing, please make sure no
wires are stuck.
ISOLATION AMPLIFIER 2284
Galvanically separated input, output, and supply
Bipolar current / voltage input
Signal conversion
Current and voltage output
24 VDC or universally supplied
Applicable in PELV/SELV circuits

APPLICATION:

Galvanic separation of analogue signals (ground loop elimination).
Measurement of floating signals.
Signal conversion within the ranges: -250...+250 VDC or -50...+50 mA on the
input and 0...10 (20) VDC and 0...20 mA on the output.

DESCRIPTION:

The 2284 uses microprocessor technology for the selection of gain and zero off-
set, yet the signal processing is analogue with a fast response time of less than
25 ms.

TECHNICAL CHARACTERISTICS:

In standard ranges, the 2284 is programmable within the input and output
ranges using internal dipswitches.
Provided that the front adjustments are still sealed, the unit needs no readjust-
ment after programming.
The unit is galvanically separated between input, supply, and output.

INPUT:

Current or voltage in standard or special ranges within the measurement range.
The programming schedule shows the standard ranges. Nominal standard input
resistance is 50 Ω for mA signals. The 2284 has a 2-wire transmitter supply and
a reference voltage of 2.5 VDC, max. 15 mA for short circuit-protected supply of
potentiometers.

OUTPUT:

The output can be ordered for standard or special currents and voltages within
the signal range.
