EDAM-8510
Isolated RS-422/485 Repeater
Introduction
The EDAM-8510 repeater boosts the RS-422/485 signals to extend the reach distance up to 4000 ft
(1200 m) and increase the maximum number of connected nodes up to 128.
With a special circuitry, EDAM-8510 is able to automatically detect the data flow and switch the
direction of the data lines accordingly.
"Auto baud rate detector" enables EDAM-8510 to automatically configure RS-422/485 signals to
any baud rate without external switch setting.
Build in Opto-isolators on EDAM-8510 provides 3000 Vdc of isolation to protect the host computer
from ground loops and destructive voltage spikes on the RS-422/485 data lines.
EDAM-8510 also offers internal surge-protection on the data lines. Internal high-speed transient
suppressors on each data line protect the module from dangerous voltages levels or spikes.

Power supply
EDAM modules are designed to accept industry standard +24 Vdc unregulated power. Operation is
guaranteed when using any power supply between +10 and +30 Vdc.
Power ripples must be limited to 5V peak to peak while the voltage in all cases must be maintained
between +10 and +30 Vdc. All power supply specifications are referenced at module connector.
