Product Description:
The E4809-820-005-B Power Board is an industrial grade unit designed for robust power control. It handles three phase AC input via dedicated terminals and supports modular integration. It offers passive cooling and screw mount PCB installation. This board is well suited for demanding electrical and control applications.
The E4809-820-005-B power board’s input section is configured with UI, VI and WI terminals that accepts three phase AC supply. The primary relay in this model is an Omron G7R-2A4-ASI unit that is rated at 7 A for 250 VAC or 30 VDC with a coil voltage of 110 VAC. This relay is central to load switching and isolation functions. The board includes auxiliary relays specifically FUJI FAUX Type RY4S models. These relays operate at 110V AC and supports 50/60 Hz frequency. Resistance components include two S20 100 ΩK ceramic resistors each rated at 100 ohms. These resistors handle high energy dissipation and are designed for thermal stability. The capacitor bank includes five electrolytic capacitors each rated at 350 V and 330 µF with a + 105 °C temperature rating. These components provide energy filtering and voltage stabilization. The board features multiple header type connectors including XT1, XT2, XT6-1 and Z2. These allow modular expansion and signal interfacing. The component layout combines through hole and plug in design formats for easy service and replacement.
The Okuma E4809-820-005-B power board supports a passive cooling mechanism that ensures heat dissipation without active elements. It mounts securely onto standard enclosures via PCB screw hole supports. This makes it suitable for control cabinets or automation systems with limited airflow. All components in this E4809 series board are industrial rated and selected for durability in high temperature or high vibration environments.
