Separation of 0(4) ... 20 mA Standard Signals, 1 channel
Description

RH18-1 (1 channel) - 5 years warranty!

The loop-powered isolator RH 18 is used for the electrical isolation and processing of 0(4) … 20 mA standard current signals. Its high level of reliability, extremely compact form, and cost optimized design make the RH 18 the first choice in its class!

Numerous sensible details: For example, because of its extremely small installation depth of only 60 mm, the RH 18 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 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 RH 18 offers Protective Separation in according to EN 61140. The RH 18 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.
