DC path resistance typically remains low for the life of the relay. At the end of relay life, the
path resistance rises rapidly above 1 Ω. Load ratings apply to relays used within the
specification before the end of relay life.
Thermal EMF ≤12 μV, typical
Bandwidth (-3 dB, 50 Ω termination) ≥40 MHz, typical
Crosstalk (50 Ω termination, channel-to-channel)
10 kHz ≤-85 dB, typical
100 kHz ≤-70 dB, typical
1 MHz ≤-50 dB, typical
10 MHz ≤-30 dB, typical
Isolation (50 Ω termination, open channel)
10 kHz ≥85 dB, typical
100 kHz ≥65 dB, typical
1 MHz ≥45 dB, typical
10 MHz ≥25 dB, typical
Dynamic Characteristics
Maximum cycle speed 145 cycles/s
Relay operate time 1 ms, typical
3.4 ms maximum
Note Certain applications may require additional time for proper settling. Refer to
the NI Switches Help at ni.com/manuals for more information about including
additional settling time.
