这家伙长得有点像中继器,带个软软的长尾巴。用于将PROFIBUS站点柔性地连入到网段中。

Electrical networks (RS 485) - Bus terminals

FOr connecting PROFIBUS stations with an RS 485 interface to a segment Variants with transmission rates of 9.6 kbit/s to 12 Mbit/s
Easy, transparent assembly (simply snap onto a standard rail)
Unambiguous localization of faulty bus termination with the 12M bus terminal PG connection with a special bus terminal and PG connecting cable without the need to install network nodes for the RS 485 bus terminal.


Benefits:
Easy and clearly comprehensible connection of PROFIBUS stations thanks to preassembled, integrated connecting cable
Simple cabinet pre-wiring by connecting the PROFIBUS connecting cable with integrated interfaces

Application:
The PROFIBUS bus terminals enable a bus station to be connected to a PROFIBUS network.Pre-wired device connection for PROFIBUS node
Easy connection of stations to PROFIBUS networks through insertion of the radial line with Sub-D plug
Implementation of multipoint connections by directly interconnecting several bus terminals (up to 32 stations per segment) with the 12M bus terminal.


Design:
Different versions are available:
Up to 1.5 Mbit/s RS 485 bus terminal
Up to 12 Mbit/s 12M bus terminal.
The following is applicable to all variants:
Housing with degree of protection IP20
Wall mounting or mounting on deep standard mounting rail
External 6-pin terminal block for connecting incoming and outgoing bus cable and equipotential bonding conductors
Integrated connecting cable with Sub-D plug for connecting the nodes
Terminating resistor combination can be connected through rotary switch The 12M bus terminal has the following additional features:
Ranges can be set for data transmission rates through a rotary switch. Supply of 12M bus terminal through connected PROFIBUS node (5 V DC/90 mA) using a 9-pin Sub-D connector
For maximum segment lengths, see technical specifications.
Incoming and outgoing bus cables are isolated when the terminating resistors are inserted.


Function:
Connection of stations over flexible connecting cable with Sub D connector Easy connection of the bus cable over the terminal block
No bus interruption in response to a missing terminal
Bus termination is possible over integral termination resistor combinations.The following also applies to the 12M bus terminal
Unique localization of faulty termination within a segment (the incoming and outgoing bus cables are cut for inserting the resistor combinations)
When the 12M bus terminal is used in a segment with RS 485 bus terminals, the configuration rules for the RS 485 bus terminal apply (see manual for PROFIBUS networks).
