WARNINGS AND CAUTIONS
WARNING - HAZARDOUS ENVIRONMENTS SYMBOL
This product is not specically designed for use in hazardous environments, for example in explosive
atmospheres. If the product is to be used in hazardous environments we recommend that the user
ensures suitable protective measures are taken.
!
CAUTION - HANDLING OF ELECTROSTATIC-SENSITIVE DEVICES SYMBOL
Certain semiconductor devices used in this equipment are liable to damage due to static voltage.
Observe the following precautions when handling these devices in their unterminated state, or
sub-assemblies containing these devices:
1. Persons removing sub-assemblies from equipment using these devices must be earthed by a
wrist strap and a resistor at the point provided on the equipment.
2. Soldering irons used during the repair operations must be low voltage types with earthed tips and
isolated from the mains voltage by a double insulated transformer.
3. Outer clothing worn must be unable to generate static charges.
4. Printed Circuit Boards (PCBs) tted with these devices must be stored and transported in
anti-static bags.
WARNING - DANGER OF ELECTRIC SHOCK SYMBOL
This card may contain hazardous voltages. Before removing the card from the chassis remove all
supplies and disconnect user I/O signals.
Unused slots in the PC chassis are populated with blanking plates to prevent access to user I/O
signals that may be present. . If the product is not used in this manner for example by using an
extender card then additional care must be taken to avoid contact with exposed signals.
Not to be used in safety critical circuits, refer to the Pickering Interfaces’ terms & conditions of sale.
This card must not be used for the switching of Mains Circuits. For the switching of voltages up to
the card’s full specication, Secondary Circuit power supplies and the Device Under Test must be
fully isolated from the Mains Circuit and the safety earth.
The host chassis must be correctly installed and be connected to mains or factory safety ground,
please refer to your chassis installation manual.
Diagram Showing Separation Between The Mains Circuit and Secondary Circuit / DUT
For the purposes of this document, a Mains Circuit is an installation classied as Overvoltage
Category II up to 300V. Separation between the Secondary Circuit and Mains Circuit is achieved
by a transformer in which the primary windings are separated from the secondary windings by
reinforced insulation, double insulation, or a screen connected to the protective conductor terminal.

50-411 Relay Driver Functional Diagram
The 50-411 is the perfect solution for driving external
relays from a PCI slot.
The card provides 64 channels of low side switching for
external relays. Users need to simply connect a positive
voltage source to one terminal of a relay coil and the other
terminal to an output of the 50-411. Each output is capable
of sinking up to 1 A of continuous current.
Outputs have current, thermal and overvoltage protection.
The thermal and current limit circuits protect the output
from failure even when directly connected to voltages up to
30 V. When switching relays, spikes from the inductive load
are clamped at 80 V and relay coil energy of up to
550 m Joule can be dumped without the use of additional
diode clamps.
Relay coil current is prevented from flowing back into the
PCI slot by the use of an isolation barrier.

FUNCTIONAL DESCRIPTION
A functional block diagram is provided in Figure 2.1. The card is powered by the +3.3V and +12V supplies from the
PCI host slot via the PCI bus edge connector. The interface to the user test equipment is via the front panel mounted
78-pin D-type connector, J2. The module comprises Solid State Switches U101 to U164, Shift Registers U7 to U14,
Level Translator U5, conguration EEPROMS U2 and U3, and PCI Bridge U1. The module conguration, is stored
in EEPROM U3. U7 to U14 are loaded with serial data from PCI bridge U1 via U5. The bit pattern that appears on
the outputs of the shift registers is used to activate the required solid state switches, U101 to U164. When activated,
the solid state switches sink current enabling the user to drive external relays via connector J2. The PCI Bridge U1
is congured by EEPROM U2.

Ground Return
A typical application for the 50-411 is shown in Figure 2.2. where a single external relay is driven from one of the 64
outputs. Local power supply decoupling for the relay and coil suppression circuits are recommended for best EMC
characteristics with high current relays, but are not essential for safe operation due to the built in protection system.
Ground Return Pins
When powering relays with an external supply, the return path is provided by a total of 11 ground pins on the card’s
front panel connector. Multiple pins should be utilized to distribute the current loading. Pickering’s mating connectors
are rated at 3A per pin, consult manufacturer’s specications if alternatives are used.

PREOPERATION CHECKS (UNPACKING)
1. Check the card for transport damage and report any damage immediately to Pickering Interfaces.
Do not attempt to install the product if any damage is evident.
2. Position the PC chassis relative to any other equipment the card(s) will connect with. Ensure the chassis is
not connected to the electrical supply.
3. Ensure that the designated area for the chassis containing the card(s) is of at and solid construction to
withstand and support the total weight of the PC Chassis and cards.
SECTION 3 - INSTALLATION

SECTION 3 - INSTALLATION
SOFTWARE INSTALLATION
First install the appropriate Pickering PCI switch card drivers by running the installer program Setup.exe (provided
in a compressed zip le), either from the CD-ROM supplied, or by downloading the latest version from our website
pickeringtest.com - the recommended method. Setup is accompanied by a ReadMe le containing
additional installation information. A single installation covers all cards in the System 40, System 45 and System
50 ranges.
When installation completes, the installed drivers’ ReadMe le is offered for display. It can also be displayed
later using a shortcut on the Programs>>Pickering menu.
If you are not a LabVIEW user you should choose the “full” version, and once that has been installed run
the LabVIEW Runtime Engine installer via the shortcut on the Programs>>Pickering menu. In the absence of
LabVIEW the Runtime Engine is required to support the Pickering Test Panels application.
!
HARDWARE INSTALLATION
ELECTRICAL CONNECTION (PC CHASSIS)
1. The PCI card must be electrically installed in accordance with local regional electrical codes by a qualied
engineer.
2. The PC chassis must be grounded.
Electrostatic discharge can damage the components on the card and in the chassis. To avoid such damage
when handling the products refer to page VII.
Ensure that there is adequate ventilation.
The card should be installed in accordance with the following procedure:
1. Ensure that the system is turned OFF but still connected to mains so that it remains grounded.
2. Choose an appropriate free PCI slot in the host system.
3. Remove the blanking plate for the chosen slot and retain the xing screw.
4. Carefully remove the card from its anti-static bag and insert the card’s edge connector into the free slot in
the host system (refer to Figure 3.1).
5. Ensure the card is fully inserted into the edge connector and the front panel is fully in contact with the back
of card aperture in the host chassis.
6. Use the xing screw to secure the front panel of the card to the host chassis’ mounting rail.
7. Replace the chassis cover(s).
8. Power-up the host system.
