The 40-310/320 range of high voltage switching modules
can hot switch up to 750 V peak and cold switch up to 1000 V
peak in either general purpose relay (40-310) or multiplexer
(40-320) configurations.
These modules use high quality reed relays with switch
ratings comfortably higher than the 40-310/320 specification.
The 40-320 multiplexer allows multiple channels to be
simultaneously selected. Alternatively, product variants can
be supplied that operate as a conventional multiplexer with
break-before-make action when a new channel is selected.
Applications include; circuit board isolation testing, relay
testing, semiconductor breakdown monitoring and cable
harness insulation testing.
RFI Suppression
The 40-310/320 module includes RFI suppression that
extends relay contact life in hot switching applications and
controls surges caused by high voltage transients in cold
switching applications. The suppressors also ensure the
module’s safe operation when connected to a high voltage
source via cable assemblies that might otherwise generate
additional transients or RFI problems.
The suppression components result in reduced bandwidth
and slightly higher path resistance compared to standard
designs (please refer to the switching specification table).
Please note, it is good practice to keep high voltage
switching modules away from more sensitive units to
minimize crosstalk.

Relay Type
The 40-310 and 40-320 are fitted with high quality Rhodium
relays specifically designed for very high voltage switching
and are manufactured by our sister company Pickering
Electronics: pickeringrelay.com
The design uses through hole leaded style relays to ensure
easy replacement with no special tools required. A spare
relay is fitted to each module to enable easy servicing.
“Hot” Switching
This is when the load is switched with the high
voltage source applied. Hot switching may generate
considerable RFI, both within the switching module and on
interconnecting wiring. Care must be taken to suppress or
shield all cabling.
Note that any precaution which adds extra capacitance to
a cable should be taken with great care, even a very small
capacitance at high voltages can cause very large inrush
current through the module resulting in possible switch
weld and excessive RFI.
The 40-310/320 modules include extensive built-in RFI
suppression circuits that minimize RFI and surge problems.
“Cold” Switching – The Preferred Option for Reliability & Long Life.
With cold switching, the relay is operated before the high voltage
source is applied. In this case the maximum carry current is much
greater, also there will be much less stress on the reed relays,
resulting in improved reliability and life.
Most high voltage sources include a soft start facility which reduces
the likelihood of generating RFI or temporary over-voltage.
High voltage switching modules are often used for isolation testing
applications (e.g. cable, transformer or semiconductor isolation
tests), in these cases, cold switching is nearly always the preferred
option to reduce the risk of high voltage transients that may cause
premature breakdown.

Ensure that there is adequate ventilation.
The module should be installed in accordance with the following procedure:
1. Ensure that the system is turned OFF but still connected to mains so that it remains grounded.
2. Choose an appropriate slot in the rack.
3. Remove the blanking plate for the chosen slot.
4. Ensure that the injector/ejector handle is in its downward position. Align the module with the card guides on
the top and bottom of the slot.
Do not raise the injector/ejector handle whilst inserting the module as the module will not insert properly.
5. Hold the handle whilst slowly sliding the module into the card guides until the handle catches on the injector/
ejector rail (refer to Figure 3.1).
6. Raise the injector/ejector handle until the module rmly seats into the backplane. The front panel of the
module should be ush with the front panel of the chassis.
7. Secure the front panel of the module using both screws to the chassis front panel mounting rails.
8. In a system employing a remote control interface to connect an external controller to a PXI chassis or to link
multiple chassis, power-up the system as follows:
a. For a system comprising an external controller and one chassis, power up the chassis before powering up
the external controller.
b. For a system comprising more than one chassis, turn ON the last chassis in the system followed by the
penultimate, etc, and nally turn ON the external controller or chassis containing the system controller.
9. For Pickering Interfaces modular LXI installation there is no requirement to use any particular power up
sequence.
