HDSP RS485P
Article number: 56 055- Two-stage surge protection of connected RS485 bus device in Half-Duplex configuration with power line.
- 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.
- High-speed current protection of data line X1-2, X3-4 200 mA.
- Maximum current load of the power line 5 A.
