Product Details
Specifications

FD690 – Diameter Correction Amplifier Card – This card has four amplifiers. Three of the amplifiers have memory units which control the circuit gain. The fourth amplifier has no memory unit; its gain is controlled by a potentiometer adjustment. This, in turn, becomes a reference for the other three amplifiers.

The cards plug into sockets mounted on the panel base. Connecting pins in each plug are mated such that the circuits on each card are connected through wiring in the panel or other cards and to the connector pins.
