Specifications
Output Specification
No. of Output Channels: 32
Output States: Driven high, driven low or off.
Low Side Driver Output
Resistance:
0.6Ωat 0.5A
High Side Driver Output
Voltage:
Vext less 1.5V at 0.4A
Maximum Current: 0.5A for Low Side drivers,
0.4A for High Side drivers,
8A module total.
Maximum Voltage: +50V*
Output Protection: Current limited, overvoltage
limited, thermal protection.
Overvoltage limit can be used
to limit back emf generated from
inductive loads such as relay
coils.
Vext: User supplied +5V to +50V*,
applied to multiple pins of user
connector, relative to front panel
ground.
* For full voltage rating, signal sources must be fully isolated from
mains supply and safety earth.

PXI & CompactPCI Compliance
The module is compliant with the PXI Specication 2.2. Local Bus,
Trigger Bus and Star Trigger are not implemented.
Uses a 33MHz 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
Single slot 3U PXI (CompactPCI card).
Module weight: 180g.
3D models for all versions in a variety of popular le formats are
available on request.
Connectors
PXI bus via 32-bit P1/J1 backplane connector.
Signals via front panel 78-pin male D-Type connector, for pin outs
please refer to the operating manual.
Input Specification
No. of Input Channels: 32
Logic Threshold: Compares selected input
voltage against two reference
voltages, each of which can be
set from 0.3 to 50V with 12.5mV
setting resolution.
40-412-101 uses faster parallel
acquisition from a common pair
of threshold voltages.
Settling Time: 5μs following a state change.
Read back time for all 32 states
50μs typical.
Channel Selection: Single channel selection or
automated sequential access to
all 32 channels.
Maximum Input Voltage: 100V*
Input Impedance: 1MΩ
* For full voltage rating, signal sources must be fully isolated from
mains supply and safety earth.
