Between the channels and backplane bus
Between the channels and power supply of the
electronics
Permitted potential difference
Between different circuits
60 V DC / 30 V AC; Isolation measured for 120 V
AC basic isolation: Between the channels and
supply voltage L+, between the channels and the
backplane bus, between the channels
2000 V DC between the channels and the supply
voltage L+, 2000 V DC between the channels and
the backplane bus, 2000 V DC between the
channels, 707 V DC (type test) between the sup-
ply voltage L+ and the backplane bus

Cable compensation is performed alternately to
measurement with the R/RTD three-wire meas-
u
rement. Two module cycles are thus required for
a measured value.
