ATC-109N
RS-422/RS-485 Photoelectric Isolation Data Repeater
General introduction
ATC-109N data repeater is a kind of data relay communication product of photoelectric isolated RS-422/RS-485.
It can be used with ATC-109N Photoelectric Isolation Interface Converter in combination. ATC-109N data repeater can prolong the communication distance of RS-422/RS-485 bus network and increase the number of RS-422/RS-485 bus network devices. The inner circuit of ATC-109N Photoelectric Isolation Data Repeater can detect data direction and switch to
control it automatically, conveniently to form a RS-485 network without any shake hand signal. This kind of RS-485 control is fully transparent and need not amend software for the former network basing on RS-422/485 working modes. The built in photoelectric isolator and DC/DC converter can offer 3500V isolation voltage and the rapid Transient Voltage Suppressor (TVS) can effectively inhibit lightning and ESD, provide 1000W lightning strike and surge protection power on each line, and prevent lightning strike and common code interference
Performance Parameter

- Protecting grade: RS-422, RS-485 interface 1000W lightning strike and surge protection on each line
- Extended distance: 0-5 kilometers
- Working environment: -25°C to 70°C, 5% to 95% relative humidity
Installation setup and application
Please read the User’s Manual carefully before installing ATC-109N Photoelectric Isolation Data Repeater. Connect the product’s power converter with +9V socket. The Terminal pin shall be connected with RS-422 or RS-485 network equipments according to definition instruction.
ATC-109N Photoelectric Isolation Data Repeater supports following 3 relay communication modes:
A. RS-422/ 4 wire full duplex relay
B. RS-485/ dual-line half duplex
C. 4 wire RS-485 to 2 wire RS-485 relay
Power and surge grounding protection
External power supply
ATC-109N Photoelectric Isolation Data Repeater can adopt the product’s DC9V power adapter for power supply or adopt power from other DC power or device. The power supply voltage is +7.5V—+24V, current 100mA. The connection pins are Terminal: V+,V-
Surge grounding protection
Common repeater has no large energy protector. The transient high voltage induced in interface data line tries to release energy to the ground wire via the minimum resistance route of the device and thus can easily cause damage to interface parts. ATC-109N Photoelectric Isolation Data Repeater can provide 1000W lightning strike and surge protection power on each line. The rapid Transient Voltage Suppressor (TVS) can effectively inhibit lightning and ESD. ATC-109N Photoelectric Isolation Data Repeater terminal Pin FGND is designed for surge grounding protection.
The user shall try to avoid hanging by credible grounding to ensure the safety of communication during operation.
