6 2284V104-UK
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 offset,
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 DIP-switches.
Provided that the front adjustments are still sealed, the unit needs no readjustment
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.
