INTRODUCTION

Accessory 8D (ACC-8D) Option 4 is a standalone printed circuit board that typically is connected
to PMAC via ACC-8D (the Terminal Block board). Option 4 provides four 40W continuous
(60W intermittent) linear amplifiers. The amplifiers may be used to drive small DC motors or
proportional hydraulic valve actuators. The Option 4 board has a compact size. It may be
interfaced conveniently to PMAC through ACC-8D and through a 16-pin flat cable. To bring the
analog command and digital amplifier-enable signals to this board, connect J5 of the main ACC­8D board to J1 of Option 4 board with the provided 16-pin flat cable.

CONNECTORS

J1

This connector brings in up to four analog command signals and amplifier-enable lines from the
ACC-8D board via its J5 connector through the provided 16-pin flat cable. A listing of J1 pin
definitions can be found in this manual.

TB1

This terminal block provides the actual connection to the motors or hydraulic valve actuators.
Also, the power supply for this board must be brought in through this connector. A listing of
TB1 pin definitions can be found in this manual.

TB2

This terminal block provides the dither signal input.
