2.4. ISOLATION
ADA-4040PC6 converter has 3-way galvanic isolation on the levels 1kV= or 3kV=, depend on version described in section
VERSIONS.
Fig 2. Isolation structure
3. INSTALLATION
This chapter will show how to use and connect ADA-4040PC6 to RS485, RS422 network and power supply.
In the purpose of minimization of disruptions from environment is being recommended to:
- apply multipair type shielded cables, which shield can be connected to the earthing on one end of the cable,
- arrange signal cables in the distance not shorter than 25 cm from powering cables.
- apply cable of adequate cross-section due to voltage drops for converter powering,
- use suppression filters for powering converters that are installed within a single object.
- not supply converter from power circuit device that generates large impulse interference such as transmitters, contactors.
3.1. ASSEMBLING
The cover of ADA-4040PC6 is adapted to assembly on TS-35 (DIN35) rail. To install the converter, should be mounted on the rail
upper part of the cover then press bottom part to hear characteristic „Click” sound.
3.2. COMPUTER CONNECTION
To connect ADA-4040PC6 to computer is needed additional converter e.g. ADA-I9141 USB to RS485/RS422 converter; connected to
NMEA (5-pin connector) port of the converter.
Typical connections of ADA- 4040PC6 to PC are shown bellow.
Fig 3. 4-Wires connection of ADA-4040PC6 to PC by the use of ADA-I9141 – USB to RS485/RS422 converter.
Fig 4. 2-Wires connection of ADA-4040PC6 to PC by the use of ADA-I9141 – USB to RS485/RS422 converter.
3.3. RS485 NETWORK CONNECTION
RS485/RS422 interface in ADA-4040PC6 converter is available on terminal block, described as: Tx+/A, Tx-/B, Rx+, Rx-, and
connection to RS485(4W) and RS485(2W) bus are shown bellow.
ADA-4040PC6 connect to eg. FURUNO GP-150 by the use of signal cable NMEA0183 7-pin 5 m (MJ-A7SPF0003-050C), according to
below specification.
