HDSP RS485/422

Two-stage surge protection of connected RS485/422 bus device in Full-Duplex configuration.
They are installed prior to the protected equipment and at the interface of LPZs 1 – 2 and higher.
They increase the EMC level of the connected equipment against switching and atmospheric transients tested according to IEC 61000-4-2 (ESD level 4), IEC 61000-4-4 (EFT level 4) and IEC 61000-4-5 (shock pulse level X = 6 kV).
The connection of the module allows to use the operating range of bus drivers according to the TIA/EIA-485-A standard in the range of -7 V to +12 V (common-mode voltage range).
Connecting the module allows you to use the full 10 Mbps bus speed according to the TIA/EIA-485-A or TIA/EIA-422-B standard.
High-speed current protection of data line X1-2, X3-4, X5-6, X7-8 200 mA.
For extended protection of the common reference wire and bus shielding, use the additional mudule 1GDT/70.
