Application Example Loop-Powered Isolators The loop-powered isolator is used for electrical isolation and processing of 0(4) to 20 mA standard signals. The galvanic isolation guarantees reliable decoupling of the sensor circuit from the processing circuit and prevents linked measurement circuits from influencing each other. The Protective Separation with high isolation level provides protection for personnel and downstream devices against impermissibly high voltage. Functioning: The input signal is modulated and then electrically decoupled using a transformer. The isolated signal is then made...

Passive Isolator DH 18Separation of 0(4) ... 20 mA Standard SignalsThe input loop-powered isolator DH 18 is used for the electrical isolation of 0(4) ... 20 mA standard signals. The DH 18 transfers the measuring signal to the output with a high degree of accuracy and avoids interference voltage carry-over and suppressing interferences effectively. The slim housing with 1 1.2 mm wide for one or two channels saves significant space on the DIN-rail. Intelligent design and their consequential avoidance of highly integrated components result in extremely long service lives and reliability without...

Passive Isolator DH 1000Separation of 0(4) ... 20 mA Standard Signals The input loop-powered isolator DH 1000 provides galvanic separation for 0(4) ... 20mA standard signals, while transferring the measurement signal to the output with a high degree of accuracy. In this way, the unit avoids interference voltage carry-over, effectively suppressing interference. The very low drop voltage of 2.0 V, a high level of accuracy and a compact design all work together to make the DH 1000 the first choice in system design. The slim housing with 12.5 mm width for one or two channels saves space in your switch...

Passive Isolator DH 11000Separation of 0(4) ... 20 mA Standard Signal CC The input loop-powered isolator DH 11000 provides galvanic separation for 0(4) ... 20 mA standard signals, while transferring the measurement signal to the output with a high degree of accuracy. The unit avoids interference voltage carry-over and effectively suppressing parasitic noise. The very low drop voltage of 2.3 V and the high level of accuracy work together to make the DH 1 1 000 the first choice in system design. Intelligent design and their consequential avoidance of highly integrated components result in extremely...

Application Example The repeater power supply is used to supply and separate 2-and 3-wire transmitters and active sensor signals. Additionally the measuring input accepts active 4 to 20 mA signals from 4-wire transmitters. The galvanic isolation across input and output protects against erroneous measurements due to parasitic voltages or gorund loops. To protect both maintenance personnel as well as downstream equipment against impermissibly high voltages, the repeater offers Protective Separation in according to EN 61140. The input signal is modulated and then electrically decoupled using a transformer....

Passive Transmitter Repeater DC 58Powering and Isolation of 2-wire transmitters The Passive Transmitter Repeater DC 58 is used for powering of 2-wire transmitters and isolation of 4 ... 20 mA standard signals. The 24 V power from the control system is transferred to the 2-wire transmitter with low voltage drop. The transmitter loop current is available galvanic isolated on output of the DC58. Additionally the measuring input accepts active 4 ... 20 mA signals from 4-wire transmitters. For communication with HART-Transmitters the internal 250 Ohm resistor on terminal 4 can be used.
