PXI & CompactPCI Compliance
The module is compliant with the PXI Specification
2.2. Local Bus, Trigger Bus and Star Trigger are not
implemented.
Uses a 33 MHz 32-bit backplane interface.
Safety & CE Compliance
All modules are fully CE compliant and meet applicable
EU directives: Low-voltage safety EN61010-1:2010,
EMC Immunity EN61326-1:2013,
Emissions EN55011:2009+A1:2010.
Mechanical Characteristics
Double slot 3U PXI (CompactPCI card).
3D models for all versions in a variety of popular file
formats are available on request.
Connectors
PXI bus via 32-bit P1/J1 backplane connector.
Signals via 2 front panel 8-pin male power D-Type
connectors, for pin outs please refer to the operating
manual.
Relay Type
The 40-191A is fitted with solid state MOSFET switches.
Switching Specification
Switch Type Solid State MOSFET
Max Switch Voltage:
Continuous Switch Current:
Peak Current:
±40 V* (DC or AC peak)†
30 A continuous, all channels.
40 A continuous for single
relay (other relays carrying
<10 A).
120 A for 200 µs
Max Total Module Current:
Max Fault Bus Current:

30 A on thru path ‡
40 A, each bus
Initial On Path Resistance:
Leakage Current (at ±40 V):
6 mΩ at 25 ˚C typical
<1 µA at 25 ˚C and switch cold,
<5 mA at max temperature
immediately after switch has
carried maximum current for
>10 minutes.
Rise/Fall Time:
Operate Time:
Max Operating Speed at
nominal load:
40 µs/140 µs (typical)
250 µs
60 operations/sec
Expected Life (operations): Indefinite when used within
ratings
* For full voltage rating, signal sources to be switched
must be fully isolated from mains supply and safety earth.
† Differential voltage between channels must not exceed
rated voltage, additional caution should be used when
applying AC voltages as multiple asynchronous supplies
can create high differential voltages between channels.
‡ The capacity of the module to carry 30 A on all channels
is chassis dependent and dependent on the number of high
power modules fitted to the chassis. Specification reflects
test conditions in a Pickering PXI chassis. Refer to supplier
for chassis cooling capacity, restrict average RMS current
over 5 minute period to 25 A per channel for chassis
meeting the minimum PXI recommendations.
