LAN Components HIM Series HIM-7101
Interface
DIP
FEATURES
• Conforms to EIA RS-485 standards.
• A line driver port and line receiver port are built-in.
• An insulated DC to DC converter provides output voltage
stability and EMC prevention that are superior to units
employing the charge pump method.
• Provides power isolation from external loads (5V, 100mA).
• The use of an aluminum board ensures high withstand voltage
and low leakage.
