(40-191B versions with hardware interlock option)
*Mating half supplied when hardware interlock option
ordered, to be wired by end user.
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:
6 channels each carrying
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.
PXI & CompactPCI Compliance
The module is compliant with the PXI Specification 2.2. Local
Bus, Trigger Bus & 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.
