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 40-611A Very High Density multiplexer module is available
in 158-Channel 1-Pole or 79-Channel 2-Pole congurations. It
uses high quality electro-mechanical signal relays allowing the
switching of current up to 2A and voltage up to 300VDC/250VAC.
The module is suitable for signal routing in high channel count
ATE and data acquisition systems. Connections are made via a
front panel 160-pin DIN 41612 connector.
The 40-611A can be operated as a conventional multiplexer
with break-before-make action when a new channel is selected.
Alternatively, the 40-611A-002 can be supplied as a variant that
allow multiple channels to be simultaneously selected.
Note: Multiple channel selection is not available for the 40-611A-
001 multiplexer.
Model 40-611A channel selection congurations have been
revised from model 40-611. The 40-611A defaults to single
channel selection with the 40-611A-002 multiple channel selection
variant dened by use of a sufx.
It should be noted that the isolation relays operate automatically
when a multiplexer channel is energized.
Larger multiplexers may be constructed by daisy chaining the
common signals from multiple modules (see example diagram
overleaf). Built in automatic isolation switching connects only the
currently active multiplexer to the analogue common, this minimizes
capacitive loading and leakage currents in large multiplexer systems.
Automatic isolation switching only applies to single channel selection
mode, for versions with multi channel selection, the isolation relays
are controlled separately from the channel relays. To prolong contact
life of the isolation relays it is strongly advised that they are cold
switched.
