Connectors
PXI bus via 32-bit P1/J1 backplane connector.
Resistor channel signals via front panel 37-pin male D-Type
connector.
Relay Type
The 40-295/296 is tted with Reed Relays (Sputtered Ruthenium
type), these offer very long life with good low level switching
performance and excellent contact resistance stability.
All reed relays are manufactured by our sister company Pickering

* For full voltage rating, signal sources must be fully isolated from
mains supply and safety earth.
† Overall accuracy of module is a combination of the tted resistor
accuracy and the relay/track resistance that makes up the residual
path resistance.
