Digital Output Card Datasheet
Introduction
The 8-channel Digital Output Card can be used to switch a wide variety of DC operated devices at up to 30
Volts and 4 Amps. The outputs are opto-isolated low-side switches. All the common terminals are connected
together. Each of the output circuits is connected, via a diode, to a single zener clamp so that over voltages
from inductive loads are handled safely. This clamp is available on two terminals of the connector.

The unit links to the I C Bus connector on an Application Board. Up to 8 of these cards may be attached to
the bus (depending on how many other digital channel based cards are also used). Another 8 may be
attached if appropriate driver devices are substituted. See More than one card below for more information.
