2.4. ISOLATION
Converter ADA-1044H has 2-way or 3-way and 1kV= or 3kV= galvanic isolation (depend on version, described in section VERSIONS).
Fig 2. Isolation structure
3. INSTALLATION
This chapter will show you how to connect ADA-1044H to PC or controller with RS232 port, RS485/422 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 Interference suppression filters for power supply 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 ADA-1044H enclosure is adapted to assembly on TS-35 (DIN35) rail. To install repeater you should mount device on the rail
upper part of the enclosure then press bottom part to to hear characteristic „Click” sound.

3.2.1. CONNECTION OF DEVICES WITH RS232 PORT - DTE TYPE (COMPUTER)
To connect the ADA-1044H to RS232 computer port, is required RS232 extension cable, for example CAB-DB9F/DB9M-S-1,8m
available in our offer. Connection example is shown below.
