R3D series analogue distributors, are used for industrial automation system, supplying power to instrument of two-wire system in industrial on-site field receiving 4 ~ 20mA signal outputed from on-site instruments and transform to DCS/PLC through isolation at the same time. It characterized by the matching of signal types, signal amplification, isolation anti-interference, etc. between two-wire system in industrial on-site and DCS/PLC. Products of this series have the function of 4-20mA signal isolator through varied connections. It contains a variety of combination forms like one-input & one-output, one-input & two-output, two-input & two-output, etc. Width of the shell is only 12mm, which satisfies the high-density requirements of on-site installation.
Typical application
Ø Field where on-site two-wire instruments need distribution power supply.
Ø Field existing grounding potential difference.
Ø Field existing heavy electromagnetic interference.
Ø Protecting DCS or PLC system.
Ø Distributing one signal in two ways.
