Repeater Power Supply HART DC 52500
Powering and Isolation of SMART Transmitters with HART Communication
The Repeater Power Supply DC 52500 is used to supply and separate 2- and 3-wire SMART Transmitters and active sensor signals with HART communication.
- Universal operation of SMART Transmitters
Energization and separation of field located 2-, 3- and 4-wire transmitters - Bidirectional HART transmission
HART data transfer for repeater and isolator operation - 3-Port isolation
Protection against erroneous measurements due to parasitic voltages or ground loops - Extremely slim design
6.2 mm slim housing for a simple and space saving installation - Optional In-Rail-Bus mounting rail connector
allows for fast and economical installation - Protective Separation acc. to EN 61140
Protects service personnel and downstream devices against impermissibly high voltage - 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)
It supplies the transmitter with power and transmits the measuring signal with high accuracy galvanic isolated to the output. Alternative the measuring input accepts active 0/4 to 20 mA signals from 4-wire transmitters.
In addition to the analog signal, the DC 52500 also transmits data protocols for HART communication. It allows bidirectional communication with the field device from every point of the cabling.
The auxiliary power can be supplied via the connection terminals or via the optional In- Rail-Bus connector. A green LED on the front of the unit has been provided to monitor the power supply.
