Introduction
The PCL-734 offers 32 isolated digital output channels on a PC add-
on card. Its isolated output channels provide 1,000 V of protection.
Each I/O channel corresponds to a bit in a PC I/O port. This makes the
PCL-734 very easy to program.
Features
• 32 isolated digital output channels
• High output driving capacity
• High-voltage isolation on isolated output channels (1,000 VDC)
• Open collector outputs (up to 40 VDC)
• D-type connectors for isolated output channels
• High sink current on isolated output channels (200 mA/channel)
• Suppression diode for inductive loads
Applications
• Industrial ON/OFF control
• Contact closure monitoring
• Switch status sensing
• BCD interfacing
• Digital I/O control
• Industrial and lab automation

6 PCL-734 User's Manual
Initial inspection
We carefully inspected the PCL-734 both mechanically and electrical-
ly before shipment. It should be free of marks and in perfect order on
receipt.
As you unpack the PCL-734, check it for signs of shipping damage
(damaged box, scratches, dents, etc.). If it is damaged or fails to meet
specifications, notify our service department or your local sales
representative immediately. Also, call the carrier immediately and
retain the shipping carton and packing material for inspection by the
carrier. We will then make arrangements to repair or replace the unit.
Discharge any static electricity on your body before you touch the
board by touching the back of the system unit (grounded metal).
Remove the PCL-734 card from its protective packaging by grasping
the rear metal panel. Handle the card only by its edges to avoid static
electric discharge which could damage its integrated circuits. Keep the
antistatic package. Whenever you remove the card from the PC, please
store the card in this package for protection.
You should also avoid contact with materials that hold static electricity
such as plastic, vinyl and styrofoam.
Switch and jumper settings
The PCL-734 card has one function switch and three jumper settings.
The following sections tell how to configure the card. You may want
to refer to the opposite page for help identifying card components.
Base address selection (SW1)
You control the PCL-734's operation by writing data to the PC's I/O
(input/output) port addresses. The PCL-734 requires four consecutive
address locations. Switch SW1 sets the card's base (beginning)
address. Valid base addresses range from Hex 200 to Hex 3F0.
However, other devices in your system may be using some of these
addresses.
