Description

These modules are PCBs 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 mainly of transistors, diodes, resistors, capacitors, and jumpers.

All the cards have various quality control stamps on one or both sides of the PCB.

This catalog number consists of the following logic module quantities and types:
FB50 1 DC flip-flop
FB51 2 Dual flip-flop
FB52 3 Triple flip-flop
FC15 2 Counter flip-flop
FC17 3 Universal flip-flop
FC19 3 DC flip-flop
FC20 2 Basic flip-flop
FH15 1 Counter flip-flop
FH17 2 Universal flip-flop
FH19 3 DC flip-flop
FH20 6 Basic flip-flop
FL21 2 Basic flip-flop
