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.

CAUTION - PRODUCT DOCUMENTATION SYMBOL

Suitably qualied & trained users should ensure that the accompanying documentation is fully read

and understood before attempting to install or operate the product.

SAFETY INSTRUCTIONS

All cleaning and servicing requires the equipment to be isolated and disconnected from the power source and user I/O

signals (refer to the Maintenance Section).

• Appropriate manual handling procedures should be followed as dictated by the weight of the individual module or

the combined weight of the modules & chassis.

• Should a fault occur with the module or chassis, immediately isolate and disconnect the incoming power to the

chassis and the user I/O signals.

• Ensure the equipment is installed, operated and maintained by trained and authorised personnel.

• For suitably equipped products in the event of an emergency press the red “emergency stop” button situated on

the front of the unit.

The 50-295A is a programmable resistor card with up

to 18-channels of 8-bit resolution resistor chains in a

single PCI slot. The ﬂexible architecture allows the card

to be supplied with 12-bit, 16-bit or 24-bit resolution for

applications requiring ﬁner resolution, greater resistance

range or higher channel count. The card is ideal for

simulating sensors for control and management systems

under test, allowing the user to verify responses in design

veriﬁcation or manufacturing test applications.

The 50-296A version of the card is conﬁgured as a

potentiometers with two end connections and a wiper for

simulating adjustable components.

Versions with other resistor values can be provided for

speciﬁc applications. The resistor chains include an offset

resistor that can be used to set the minimum value.

Requests for these versions can be entered on a simple

web based form from the Pickering Interfaces web site,

allowing users a quick and easy way of obtaining a

quotation.

The card is available in a variety of densities that allow the

user to select the most appropriate solution in terms of

density and cost for an application. The card’s high channel

count enables large systems to be simulated with minimal

PCI slot occupancy.

All switches are instrument grade reed relays with low

thermal offset voltage to ensure accurate operation under

all conditions and a long service life.

To give maximum accuracy each resistor chain has

on-board E2PROM, this allows accurate calibration data to

be recorded.

The card is supplied with VISA drivers and a soft front

panel.
