Hardware Interlock
All versions of the 40/42-153 are available
with an optional hardware interlock. The
interlock, when activated, will return all
relays to their default unpowered state
(assuming the relays are fully functional)
and also provide error notification via the
software interface. The interlock feature
can be daisy-chained between additional
hardware interlock enabled modules for
example to allow one signal to disable
multiple cards. For further details please
refer to the Hardware Interlock section

FUNCTIONAL DESCRIPTION
Figure 2.1 - SPST 5A Power Relay Module (40/42-153): Functional Block Diagram
A functional block diagram is provided in Figure 2.1. The module is powered by +5V and +3.3V (PXI) or +3.3V and
+12V (PXIe) supplies via the backplane connectors. Depending upon the model number, the interface to the user
test equipment is via one or two front panel mounted 50-pin SGMC connectors, a 50-pin D-type or a 37-pin D-type
connector. The module comprises a PCB populated with 50, 36, 25 or 18 SPST electro-mechanical relays. The
relays are energised via control signals from relay drivers U11 to U18. The relay drivers are addressed by PCI bridge
U1 to output the required signal. Module conguration and PCI Bridge conguration is stored in memory devices.

MAXIMUM FREQUENCY OF OPERATIONS AT FULL LOAD
At full load breaking contacts can create a signicant amount thermal load inside the relays by the generation of
strong signal arcs. If the relays are operated near full load then the rate of operations (a complete on and off cycle)
should be limited to a repetition rate of 0.3Hz to avoid the resulting heat damaging the relay plastic components.
Repeated operation at closer time intervals under full load will result in premature relay failure.

SECTION 2 - TECHNICAL DESCRIPTION
HARDWARE INTERLOCK
The 40/42-153-xxx-HI modules have an interlock feature that can be used to return the relays (assuming they are
fully functional) to their default unpowered state if the interlock connector is not in place or if the connection between
the two interlock pins is open-circuit.
Note: The mating half to the hardware interlock connector is supplied with the module in an unwired state,
the user must implement the link connections as detailed in this section to permit operation of the module.
The user connector has the following control pins:
●Pin1: A 3.3V output from a 100Ω series protection resistor
●Pin2: An Enable pin which is by default pulled low by a 10kΩ resistor. NO RELAYS WILL BE
SWITCHED BY THE MODULE UNLESS THIS PIN VOLTAGE IS RAISED TO 3.3V.
The pin can be raised to 3.3V by connecting to the supplied 3.3V pin above. This is a global Enable for
all the relays on the module. If the Enable pin is allowed to be set low then the module will continue to
disable the relay operation until the software resets the channels to be on.
●Pin3: A Status Readback pin which is raised to 3.3V when the Enable pin is set high AND the software
has reset the module to enable relay control. This is available as physical signal on the user connector
and its status can be read back by the software driver.
●Pin 4: A connection to PXI Ground
The interlock can be used in a variety of ways when multiple modules are used in a system:
●All the Enable pins can be linked together and a single switch used to pull the Enable high to 3.3V. The
enable pin can be pulled high using a user connection. The software driver can then enable or disable
individual channels.
●All but one of the Enable pins can be connected together and connected to the Readback Status pin
of one of the modules (Master Module). The Master Module then has its Enable pin connected high
(3.3V). To restart the system the software driver would then have to enable each module through the
Master Module’s Module Enable and then turn on each 40/42-153 through its Module Enable.
●Each module can be independently controlled by linking its Enable pin to its 3.3V pin, if the user
connector is disconnected or if the link between the interlock pins is open-circuit all the relays will return
to the default unpowered state and will require restarting through its software driver control.
●The Status Readback output from one module can be connected to the Enable of the next module in
the series chain. Disconnection of the user connector or if the link between the interlock pins is open-
circuit will result in the relays of all the modules further returning to their default unpowered state. As in
the previous cases when the user connection is re-established the software driver will need to restart
the system.
It should be emphasized that if the Enable pin of the module is set low, even temporarily, the module will not
automatically turn back on when the Enable returns high. The software driver must be used to turn the channels
back on.
If required, spare / replacement hardware interlock connector(s) can be purchased, please refer to Support Products
in Section 1 for details.

HARDWARE INSTALLATION
ELECTRICAL CONNECTION (CHASSIS)
1. The chassis must be electrically installed in accordance with local regional electrical codes by a qualied
engineer.
2. The chassis must be grounded.
Electrostatic discharge can damage the components on the module. To avoid such damage in handling the
board refer to page VII.
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.
