RH1021 - 5 years warranty!
The loop-powered isolator RH 1021 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 carryover, 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 RH 1021 the first choice in system design.
Intelligent design and their consequential avoidance of highly integrated components result in extremely long service lives and reliability without any falsification of the measurement signal.
To protect both maintenance personnel as well as downstream equipment against impermissibly high voltages, the RH 1021 offers Protective Separation with a test voltage of 4 kV AC.
The RH 1021 requires no additional power supply since the auxiliary power is obtained from the input signal without distorting it. This not only saves costs during installation, but also increases reliability.
