CHAPTER General 1 information Chapter 1 General information 1
Introduction The PCL-734 offers 32 isolated digital output channels on a PC addon 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.
Specifications Digital 32 output optically-isolated outputs • Output voltage: Open collector 5 to 40 VDC • Sink current: 200 mA max.

CHAPTER 2 Installation Chapter 2 Installation 5
Initial inspection We carefully inspected the PCL-734 both mechanically and electrically 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.
Card connector, jumper and switch locations Label CN1 CN2 SW1 Function Isolated output E.
We set the PCL-734 for a base address of Hex 300 at the factory.
Hardware installation Warning! TURN OFF your PC power supply whenever you install or remove the PCL-734 or connect and disconnect cables. Installing the card in your computer 1. Turn the computer off. Turn the power off to any peripheral devices such as printers and monitors. 2. Disconnect the power cord and any other cables from the back of the computer. 3. Remove the system unit cover (refer to your user's guide chassis user's guide if necessary). 4.

CHAPTER Signal 3 connections Chapter 3 Signal connections 11
Good signal connections can avoid a lot of unnecessary damage to your valuable PC and other hardware. This chapter gives pin assignments for each of the card's connectors and signal connections for different applications. Connector pin assignments The PCL-734 has a DB-37 connector accessible from the card bracket. See the figure on page 9 for the location of each connector. Pin assignments for each connector appear in the following sections. Abbreviations IDO Isolated digital output E.
Isolated Output Each of the eight isolated digital output channels come equipped with eight darlington transistors featuring common emitters and integral suppression diodes for inductive loads. If the external voltage (5 to 40 V) is connected to each isolated output channel (IDO) and its isolated digital output turns on (max. of 200 mA per channel), the card's current will sink from the external voltage. The current through each E.GND should not exceed 50 mA.

CHAPTER Register 4 format Chapter 4 Register format 15
Programming the PCL-734 is extremely simple. Each output channel corresponds to a bit in the card's registers. To turn on an output channel you write a ‘‘1” to the corresponding bit. The card requires four I/O register addresses. The address of each register is specified as an offset from the card's base address. For example, BASE+0 is the card's base address and BASE+2 is the base address + two bytes. If the card's base address is 300h, the register's address is 302h.
