OUTPUT:
The output can be ordered for standard currents and voltages or special
versions within the signal range.
Standard output current
(pin 3) 0/4...20 mA and 0/1...5 mA acc. to order
schedule with the possibility of reversal. Current limit: 23...28 mA.
Standard voltage output
(pin 2) is achieved by short-circuiting pins 2 and 3. The
current signal is available between pins 2 and 1. For voltage signals in the range
0...1 VDC, a 50
shunt (DP 2-1) is applied; in the range 0...10 VDC, a 500
shunt (DP 2-2) is applied. If both signals are used simultaneously, the mA loop to
ground must go through the internal shunt. Adjustment of 0 and 100% is possible
in the front ±10%, but please note that the basic calibration is thereby lost.

ISOLATION AMPLIFIER 2204
• Input galvanically separated from output and supply
• Current or voltage input
• Signal conversion
• Current and voltage output
• 24 VDC supply or universally supplied
• Applicable in PELV/SELV circuits
APPLICATIONS:
Galvanic separation of analogue signals (ground loop elimination).
Measurement of floating signals.
Signal conversion within the ranges: 0...10
VDC or 0...50 mA on the input and 0...20 mA and 0...10 VDC in fixed ranges on the
output.
TECHNICAL CHARACTERISTICS:
GENERAL:
The 2204 uses microprocessor technology for the selection of gain and zero
offset, yet the signal conditioning is analogue with a fast response time of less
than 25 ms.
In standard ranges, the 2204 is programmable by use of internal dipswitches
within the input and output ranges of the order schedule. Provided that front
adjustments are still sealed, the unit needs no adjustment after programming.
Universally supplied units have a 3-port galvanic separation between input,
supply, and output.
INPUT:
Current or voltage in standard or special ranges within the measuring range.
Standard input voltage: 0/0.2...1 V, 0/0.5...2.5 V and 0/2...10 V.
Input resistance: typ. 10 M
.
Standard input current: 0/1...5 mA or 0/4...20 mA.
Input resistance: norm. 50
(0/4...20 mA).
