PR Electronics Krohne Isolation Amplifier, 2284

Description: PR Electronics Krohne Isolation Amplifier, 2284 PN: 2284 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 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. 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. Standard current output: (pin 3) 0/4...20 mA, and 0/1...5 mA acc. to the programming schedule with the possibility of signal reversal. Current limit: 23...28 mA. Standard voltage output: (pin 2) is achieved by short-circuiting pins 2 and 3. The voltage signal is available between pins 2 and 1. For voltage signals in the range 0...1 VDC, a 50 Ω shunt (DP 2-1) is applied; in the range 0...10 VDC, a 500 Ω shunt (DP 2-2) is applied. Using both signals simultaneously, the mA-loop to ground must go through the internal shunt.
