Using More Than One Opto OUT24 Card._____________________________________
Several Opto DIO cards can be installed at the same time,
allowing each card to control its own set of i/o lines.
The golden rule is:- Ensure that each card is set to a
different i/o address and the ranges do not overlap!

UDN2984 Source Drivers Selected RN14, 16 and 18 installed
10K resistor networks
ULN2804 Sink Drivers Selected Remove RN14, 16 and 18
UDN2984 ULN2804 Driver Selection.________________________________
The card can be configured to use one of two types of
high voltage drive chips ULN2804 or UDN 2984 chips. Chapter
1 explains the difference and function of these two driver types.
The two jumper pins directly below and just to the left of
the driver chips is used to made the selection.
Source Driver Output Connection.______________________________
UDN2984 Drivers.
The UDN2984 chips are high voltage, high current SOURCE
drivers, output voltage range 35 to 80 Volts, these could be
directly replaced by UDN2981 drivers for output voltages in the
