GE DS3800HPRB1C1C Pulse Rate Input Board

The GE DS3800HPRB1C1C is a Pulse Rate Input Board belonging to the Mark IV DS3800 control platform. It is designed for pulse-rate signal processing and incorporates a Programmable Interrupt Controller (PIC) and programmable interval timer devices. These components provide the timing and interrupt-control functions required for processing pulse-related signals within the control system.

Functional Description

The DS3800HPRB1C1C handles pulse-rate input processing through dedicated timing and interrupt-control circuitry. The programmable interval timer devices provide timing functions, while the programmable interrupt controller manages interrupt-related operations.

In the documented Mark IV liquid-fuel control arrangement, the HPRB board is associated with pulse feedback from magnetic pickups on the fuel flow divider. The resulting pulse-rate information is made available for controller processing through the PR_MEAS digital processing path.

Hardware Configuration

The board incorporates programmable timing and interrupt-control devices. These hardware components support pulse-related timing operations and interrupt handling rather than serving as a general-purpose analog or digital I/O module.
