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.

40-619-204 Quad 32-Channel 1-Pole Multiplexer With Monitor
The 40-619 is a high density 2 A multiplexer module
available in single, dual and quad configurations using
high quality electro-mechanical signal relays allowing each
channel to switch current up to 2 A and voltage up to
250 VAC/DC.
40-619 Multiplexer Range:
40-619-401 - Single 128:1, 1-Pole with Monitor
40-619-301 - Single 64:1, 1-Pole with Monitor
40-619-302 - Dual 64:1, 1-Pole with Monitor
40-619-202 - Dual 32:1, 1-Pole with Monitor
40-619-102 - Dual 25:1, 1-Pole with Monitor
40-619-002 - Dual 16:1, 1-Pole with Monitor
40-619-204 - Quad 32:1, 1-Pole with Monitor
40-619-104 - Quad 25:1, 1-Pole with Monitor
40-619-004 - Quad 16:1, 1-Pole with Monitor
The multiplexer includes a monitor function (e.g. DMM)
where the state of the channel relays can be verified via a
channel monitor switch and a separate bus.
The module is suitable for signal routing in ATE and data
acquisition systems. Connections are made via a front
panel 160-pin DIN 41612 connector. The channel and
monitor buses can be cascaded allowing the daisy chaining
of multiple modules to create larger multiplexers.

40-619-302 Dual 64-Channel 1-Pole Multiplexer With Monitor
40-619 Architecture
This diagram shows one multi-channel, one pole
multiplexer bank with monitoring capabilities (Default
position of the relays is shown). The lower relays
(Sub-unit 1 –Channel Switches) are the multiplexer
connections to the common (in this case, C1). The
top relays (Sub-unit 2 - Monitor Switches) are the
monitor relays. All monitor relays are connected to a
common monitoring bus (in this case, M1). It operates
as a conventional multiplexer routing signals on the
channel terminals to the common “C” terminal when the
corresponding relay is energized. Each channel includes
an additional relay which can be used to monitor the
state of the channel relay by routing the “C” signal to
the “M” bus if the channel is in the open condition. In the
default state seen above, all multiplexer channel relays
and all monitor relays are open circuit. As each bank has
a common monitor channel, only one channel per bank
can be tested at any time.
To verify that the channel relays are in the open-circuit
position and that the monitor relays are operating
correctly, each monitor relay should be operated, and
the continuity measured between M and C one monitor
relay at a time. Operating the 1-form-A monitor relay
will result in a low resistance path between the monitor
and common signals; de-selecting the monitor relay will
return to the open-circuit state.
During the verification testing, if a monitor relay is
operated, but an open-circuit condition remains, it
reveals that the associated channel relay is incorrectly
positioned, which indicates a fault condition, potentially a
welded channel relay or improper test code.
