5 Years Warranty

The Transmitter Repeater DC 58 is used for powering of 2-wire transmitters. The 24 V power from the control system is galvanic isolated transferred to the 2-wire transmitter with small voltage drop. Its high level of reliability, extremely compact form, and cost optimized design make the DC 58 the first choice in its class!

Numerous sensible details: For example, because of its extremely small installation depth of only 60 mm, the DC 58 can also be installed in economical standard terminal boxes such as those frequently used for decentralized measuring points. The slim housing with 11.2 mm wide for one or two channels saves significant space on the DIN-rail.

Analog signal processing utilizing the new APT technology guarantees precise measured values with short response times and outstanding signal reproduction at the output – and all this with unparallel sturdiness and long-term stability of the insulation paths under tough industrial conditions.

To protect both maintenance personnel as well as downstream equipment against impermissibly high voltages, the DC 58 offers Protective Separation in according to EN 61140. The DC 58 requires no additional power supply since the auxiliary power is obtained from the current loop without distorting it. This not only saves costs during installation, but also increases reliability.
