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.
!
WARNING - DANGER OF ELECTRIC SHOCK SYMBOL
This module may contain hazardous voltages. Before removing the module from the rack remove all
supplies and disconnect user I/O signals.
Unused slots in the host chassis are populated with blanking plates to prevent access to user I/O
signals that may be present. Blanking panels are available to order from Pickering in a variety of
slot widths. 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 module must not be used for the switching of Mains Circuits. For the switching of voltages up
to the module’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 - 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.

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
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 40-262 is a PXI module with 6, 12 or 18 channels providing a.
cost effective method of simulating PT100 or PT1000 RTDs. The
channels also have a short and open circuit setting to simulate
faulty wiring to a sensor. The range is as follows:
• 6 Channels, 90Ω - 250Ω for PT100 RTDs (1 PXI Slot)
• 6 Channels, 900Ω - 2500Ω for PT1000 RTDs (1 PXI Slot)
• 12 Channels, 90Ω - 250Ω for PT100 RTDs (2 PXI Slots)
• 12 Channels, 900Ω - 2500Ω for PT1000 RTDs (2 PXI Slots)
• 18 Channels, 90Ω - 250Ω for PT100 RTDs (2 PXI Slots)
• 18 Channels, 900Ω - 2500Ω for PT1000 RTDs (2 PXI Slots)
All versions are suitable for simulating a temperature range of
-25°C to 410°C for their given sensor type. The use of resistance
value calls makes programming simple, an API to convert
temperature requests to resistance calls using a model of the
sensor being used is also available.

Standard Resistor Modules
For applications that do not require the precision or accuracy of our precision range,
look to our Standard Resistor range which includes models 40-280/1/2, 40-290/1,
40-292, 40-293, 40-294 and 40-295/6
Custom Resistor Modules
If our range of Resistor Modules does not meet your specic requirements, please
contact you local sales ofce to discuss your application. Customizations include:
different start and stop values, current, power, voltage, precision, accuracy, number
of channels, connector etc.
Each channel can operate with a differential input voltage range of
greater than ±15V relative to a dened common mode voltage. The
common mode voltage can be set to 0V, +12V, -12V or an external
source of up to ±50V.
The 40-262 provides a convenient system for verifying channel
resistance using an external DMM connected to the calibration
port. The system allows cascading so one DMM can be used for
the verication of multiple modules. Verication can be performed
while the UUT is connected to the module.

Typical accuracy of 40-262 over the entire
resistance range measured at 21˚C
Performance is measured in 10mΩ increments by making a
resistance call (in Ohms) to the module and then measuring
the actual resistance with a DMM. Vertical axis shows the
reading error as % of the requested value.
The 40-262 uses innovative techniques which are the subject
of protected Pickering Interfaces intellectual property rights.
Calibration Port
Function: Supports 4 terminal measurements of all
the channels in the module. Modules can
be cascaded together to permit single DMM
to support multiple modules with simulation
channel connected to UUT.
