The DS3820AISA1A1A is part of the Speedtronic Mark IV line manufactured by General Electric. The DS3820AISA1A1A is a smaller circuit board. There are three thin metal pieces with screw ports to secure the DS3820AISA1A1A in place. Each section of the DS3820AISA1A1A is labeled with a corresponding letter and number combination based on the part. The DS3820AISA1A1A sixteen large bright orange diodes, and eight small teal diodes. Didoes are used to direct energy to flow in a single direction. The DS3820AISA1A1A has a black plastic terminal with twelve flat screw ports. In front of the black plastic terminal is a small metal terminal with another twelve flat screw ports. The DS3820AISA1A1A also has a small section in the open space of the circuit board where additional parts could be added like an EPROM, EEPROM, additional diodes, capacitors, resistors, etc. The DS3820AISA1A1A has four light blue resistors with up to five colored rings to indicate how much energy was resistor can restrict at any time. The DS3820AISA1A1A has six small blue masculine terminal ports with ten metal prongs in each port. These masculine terminal ports are used to connect with other circuit boards. The DS3820AISA1A1A has four sets of pins called Jumper Ports. Jumper Ports come with small plastic sleeves to cover the pins. By covering the Jumper Ports the worker can control and direct which way the energy flows through the circuit board.
