Product Description:
The A7-1-120211-1B drive board serves as a central controlling interface specifically in systems involving electrical load switching. It is a part of Sanyo Denki which leads industries by developing exceptional products for everyday use in industrial automation.
The A7-1-120211-1B drive board works within an input voltage range of 100 V to 240 V AC. This wide input capability allows the board to be compatible with common industrial power supply systems without the need for additional voltage converters. It stabilizes incoming AC voltage internally and routes it through a combination of resistive and capacitive components for power conditioning. The operating temperature span is specified between 0°C to 70°C. All components including electrolytic capacitors, film capacitors, resistors and semiconductor elements are selected to function reliably within this range. Heat-sensitive areas are isolated and airflow channels are open to avoid overheating during extended operations. The board in terms of dimensions, measures approximately 150 mm in length, 100 mm in width and 30 mm in height. It fits well into standard equipment enclosures and control panels. The board features multiple mounting holes and connector points along the edges for secure placement and wiring.
The A7-1-120211-1B drive board’s total weight is under 1 kilogram which aids in allowing it to be mounted and serviced easily without mechanical support and needs no maintenance. The green cylindrical wire-wound resistors marked at 3.3k ohms at the 5W white film capacitors marked 250 V and black electrolytic capacitors rated at 100 micro-Farads. The right-hand side hosts a row of black heat-sinked solid-state devices used for switching operations. Small logic ICs and signal transistors are positioned to support input or output communication.
