EDAM-8510Isolated RS-422/485 RepeaterIntroductionThe 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 thedirection of the data lines accordingly.“Auto baud rate detector” enables EDAM-8510 to automatically configure RS-422/485 signals toany baud rate without external switch setting.Build in Opto-isolators on EDAM-8510 provides 3000 Vdc of isolation to protect the host computerfrom 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 transientsuppressors on each data line protect the module from dangerous voltages levels or spikes.Features• Automatic internal RS-422/485 bus supervision• No external flow control signals required for RS-485• Minimum 3000 V DC isolation protection• Transient suppression on RS-485 data lines• Supported baudrate up to 115.2 Kbps• Reach distance up to 4000 feet (1200 m)• Reserved space for termination resistors(R8,R9)• Power and data flow indicator for troubleshooting• Power requirement: +10 to +30 Vdc• Mounts easily on DIN-rail or panelSpecifications:• Power requirement: Unregulated +10 to +30 V DC with protection from power reversals• Case: ABS with captive mounting hardware• Accessories (Supplied):NYLON DIN-rail Mounting Adapter SECC Panel Mounting Bracket• Plug-in screw terminal wiring: Accepts AWG 1-#12 to #22 (0.5 to 2.5 mm) wires• Supported baudrates (bps):1200, 2400, 4800, 9600, 19.2 K, 38.4 K, 57.6 K, 115.2 K• Isolation voltage: 3000 Vdc• RS-422/RS-485 connector: plug-in screw terminal• Power consumption: 0.7W• Operating temperature:0 ~ 70 °C (32 ~ 158 °F)• Storage temperature:-25 ~ 85 °C (13 ~ 185 °F)• Humidity: 5 ~ 95%, non-condensingPower supplyEDAM modules are designed to accept industry standard +24 Vdc unregulated power. Operation isguaranteed 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 maintainedbetween +10 and +30 Vdc. All power supply specifications are referenced at module connector.EDAM-8510 user’s manual |
