Introduction
Ideal for applications such as device On/Off control or signal switching, the PCL-735 12-channel relay actuator provides 12 electromechanical SPDT relays on a half-size card.
To prevent relay fault, the On/Off status of each relay is easy to
monitor. A red LED next to each relay shows its On/Off status, and the
software can read each relay's status. Plus, an on-board DB-37
connector provides access to all output channels.
Features
• 12 relay outputs
• LED relay status indicators
• Male DB-37 matching connector included
• Relay status readback function
Applications
• Industrial On/Off control
• Signal switching
• External relay driving

Initial Inspection
We carefully inspected the PCL-735 both mechanically and electrically before shipment. It should be free of marks and in perfect order on
receipt.
As you unpack the PCL-735, 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-735 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.

Base address selection (SW1)
You control the PCL-735's operation by reading or writing data to the
PC's I/O (input/output) port addresses. The PCL-735 requires two
consecutive address locations. Switch SW1 sets the card's base
(beginning) address. Valid base addresses range from Hex 200 to Hex
3F0. Other devices in your system may, however, be using some of
these addresses.
We set the PCL-735 for a base address of Hex 300 at the factory. If
you need to adjust it to some other address range, set switch SW1 as
shown in the following table:

Hardware Installation
Warning! TURN OFF your PC power supply whenever you
install or remove the PCL-735 or connect and
disconnect cables.
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 (see the user's guide for your chassis
if necessary).
4. Locate the expansion slots at the rear of the unit and choose any
unused slot.
5. Remove the screw that secures the expansion slot cover to the
system unit. Save the screw to secure the interface card retaining
bracket.
6. Carefully grasp the upper edge of the PCL-735 card. Align the
hole in the retaining bracket with the hole on top of the expansion
slot and align the gold striped edge connector with the expansion
slot socket. Press the board firmly into the socket.
7. Secure the PCL-735 using the screw you removed in step 5.
8. Attach any accessories (using 20 pin flat cables, a DB-37 cable,
etc.) to the PCL-735.
9. Replace the system unit cover. Connect the cables you removed in
step 2. Turn the computer power on.

Relay Output
The PCL-735 has 12 channels of Single Pole Double Throw (SPDT)
Form C relay output. Each relay has two Form C contacts, which are
controlled by the same coil. One of the contacts is connected directly
to CN1 for relay output, while the other contact controls the LED that
displays the relay status, which can also be read back by a read
command to the I/O port.

A write operation to I/O address BASE+0 will change the output
status of each relay. For example, if Bit 0 of BASE+0 is set to "1"
(logic high), K0 (Relay 0) will switch from position NC0 (Normal
Close) to position NO0 (Normal Open). This means that Load 2 is
energized, while Load 1 is de-energized.
In summary, when the bit has a value of "0" (power-on default), the
corresponding COM line is in the "Normal Close" position. When the
bit has a value of "1", the corresponding COM line is in the "Normal
Open" position.
Warning: External circuits connected to the PCL-735's relay
ouput port must be fused at 1A or less and be rated
at 120 VA or less. Voltage must not exceed the
±120V peak.

Programming the PCL-735 is extremely simple. Each I/O 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. See Chapter 2 for information on setting the card's
base address.
