Isolation Amplifier Module DN 240M

The Isolation Amplifier DN 240M is used for isolation and conversion of 0 to 20 mA, 4 to 20 mA and 0 to 10 V standard signals.

Cost optimized design
Economical separation for standard applications
Calibrated signal setting
Input and output range can be set by using connector pins - without any further adjustment
Power Supply for 24 V DC
Applicable for standard power supply voltages
3-port isolation
Protection against erroneous measurements due to parasitic voltages or ground loops
Ultra-small-sized housing
15.5 mm flat module for pcb assembling
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)

Its high level of reliability and cost optimized design make the DN 240M the first choice in customer applications.

Unique in its price class, the DN 240M provides application flexibility thanks to the calibrated range.

The desired input and output range can be easily set by terminal pins and due to the calibrated range selection no further adjustment is necessary.

The flat module with 15.5 mm height for pcb assembling saves space in the customer application.
