DIN rail power distribution/distributor
anti-interference.
characteristically SPD function, lightening-protection
width: 12mm
R7D series analog lightening-protection power distributors, used for industrial automation system, supply power to the two-wire system instrument and receive 4 ~ 20mA output signal outputed by on-site instruments, then isolate it and transform to DCS/PLC. It realized the matching of signal types, signal amplification, isolation and anti- interference, etc. between industrial on-site instruments and DCS/PLC. Products of this series characteristically have SPD function, which can efficiently absorb and release the surge energy produced by (external) input induction lightening. Moreover, this product can work as 4~20 mA signal isolator through different connections. It contains a variety of combination forms like one-input & one-output, one-input & two-output, two-input & two-output, etc. The width of this shell is only 12mm, which satisfies the high-density requirements of on-site installation.
