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

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 40-681A Very High Density Versatile Multiplexer

module features a wide range of selectable switching

conﬁgurations. It is especially useful where a high density

multiplexer is required that can adapted to different

conﬁgurations for different test targets, or where a test

system may have to be reconﬁgured in the future. The

module uses high performance solid state relays which

have a long service life even when hot switching capacitive

loads. The 40-681A can sustain 1.5 A for 100 ms on hot or

cold switching.

MUX Conﬁgurations

The module can be set in software to be one of a large

number of multiplexer conﬁgurations. Switches allow the

multiplexer banks to be set as 1 or 2-pole and inter-bank

switching enables the channel count to be increased up to a

maximum of 128 (refer to schematic diagram overleaf).

Typical Conﬁgurations:

8-Banks, 16-Channel, 1-Pole

8-Banks, 8-Channel, 2-Pole

4-Banks, 32-Channel, 1-Pole

4-Banks, 16-Channel, 2-Pole

2-Banks, 64-Channel, 1-Pole

2-Banks, 32-Channel, 2-Pole

1-Bank, 128-Channel, 1-Pole

1-Bank, 64-Channel, 2-Pole

The versatility of the 40-681A’s architecture allows

all multiplexer banks to be inter-linked and common

connections used as extra signal inputs.

The 40-681A can be operated as a conventional multiplexer

with break-before-make action when a new channel is

selected. Alternatively, product variants can be supplied

that allow multiple channels to be simultaneously selected.

Isolation Switching connects only the currently active

multiplexer bank to the analog common, keeping capacitive

loading and leakage current in large multiplexer systems

to a minimum. Larger multiplexers may be constructed by

daisy chaining the common signals from multiple modules.

Pickering Interfaces is able to offer PXI solid state

switching solutions in a variety of conﬁgurations. If you

have a different requirement, contact your local sales ofﬁce

for a quotation.
