Isolation Amplifier DN 2300
Isolation of Standard Signals with ZERO/SPAN Adjustment
The Isolation Amplifier DN 2300 is used for electrical separation of 0(4) to 20 mA signals.
- Zero/Span Adjustment
Measurement range compensation on the front panel - Universal Power Pack for 20 to 253 V AC/DC
Applicable world-wide for all common supply voltages - 3-port isolation
Protection against erroneous measurements due to parasitic voltages or ground loops - Ultra-small-sized housing
12.5 mm housing with plug-in screw terminal blocks - High accuracy
No falsification of measured signal - Protective Separation
Protects service personnel and downstream devices against impermissibly high voltage - Maximum reliability
No maintenance costs - 5 Years Warranty
Defects occurring within 5 years from delivery date shall be remedied free of charge at our plant (carriage and insurance paid by sender)
The Zero/Span adjustment on the front panel, the new universal power pack, and the compact design all contribute to its application flexibility. High reliability and Protective Separation are further characteristics that contribute to fault-free equipment operation.
The slim housing with 12.5 mm width saves space in the switch cabinet and facilitates by the practical plug-in screw terminal blocks the assembly.
The new universal power pack for 20 to 253 V AC/DC means the DN 2300 can be used anywhere in the world, with all mains power supplies. The unit’s high efficiency contributes significantly to reducing the unit’s own heat generation. This is reflected in extremely high reliability and long-term stability. A green LED on the front of the unit has been provided to monitor the power supply.
