This module is a PCB intended to be inserted in a card cage. There is an extraction handle attached to the front of the card, on which a paper label containing the model number, serial number, and other information is printed.

Opposite the handle there are 47 bifurcated gold-plated contacts arranged in two rows. Mounted on the component side of the PCB are the active and passive components, consisting of transistors, diodes, resistors, and capacitors. Three of the resistors are wire-wound power resistors, and one of the transistors is a power transistor mounted on a black anodized heat sink. A linear trim potentiometer is also mounted on the PCB.

The card has various quality control stamps on one or both sides of the PCB.
