ACLD-9185
This chapter describes how to install and use the ACLD-9185.
1.1 Introduction
The ACLD-9185 is a 16-channel SPDT form C relay output board. It
provides 16 electromechanical SPDT relays, which can be used by any
ACL series or PCI series boards with digital output channels on 20-pin flat
ribbon connector.
You can use the 16 on-board relays to control power switches. Each of
them matches with one LED to indicate its ON/OFF status and consumes
about 33mA when energized. When all relays on the board are active,
the board takes about 0.53 A from the computer's 12 volts power supply.
When the current driving capability of the 12V power source is not enough,
the ACLD-9185 has a jumper switch allowing the users to connect an
external +12V power source.
1.1.1 Features

l 16 Single-Pole-Double-Throw relays
l LED indicators to show activated relays
l On-board relay driving circuits
l 120V/1 Amp contact rating
l Simple to program
l Controlled through TTL/CMOS signals or digital output ports
of any ACL and PCI series board
