Isolation
Channel-to-channel, channel-to-Vsup, channel-to-earth, Vsup-to-earth (up to 5,000 m)
[2]
Continuous 60 VDC, Measurement Category I
Withstand 1,000 Vrms, verified by a 5 s dielectric withstand test
Caution
Any excitation output voltage to earth ground must remain
below 60 VDC for each channel. To determine excitation output voltage to
earth ground for a channel, add the maximum excitation voltage to the
maximum potential on pin 3. The maximum excitation voltages are 2 V
+3% and 3.3 V +3% for the bridge excitations, 12 V +5% for the +12 V
excitation, and 22 V for the IEPE excitation.
1
The maximum voltage between pin 2 and pin 3 on a single connector is -20 V to
+30 V.
2
Must use crimp contact LEMO plug (784162-01) to maintain these ratings. Ratings
are invalidated if solder version is used.
