Temperature transmitter Ex i
Series 9182
Signal duplication of the input wiring in 2-channel Types 9182/20-5d-1f
(d=0.1; f=1.2)
• For two-channel ISpac 9182, both multiplexed Ex i inputs can be switched to a sensor
in parallel. Signal duplication is both functional and possible in terms of safety (Ex i).
8.3.3 Connection of Supply
8.3.4 Reference Junction Compensation
If "external reference junction in two-tier terminal" is selected:
• Set the DIP switch "S2" to "1" or
• and select corresponding setting in the ISpac Wizard.
a) External reference junction
Using the external reference junction in the form of a top hat rail terminal
(9191/VS-03 or 9191/VS-04) allows a higher accuracy of measurement to be achieved
based on temperature thanks to the separation from heat sources.
• Install the reference junction on a top hat rail so that it is spatially separated from heat
sources.
• Connect reference junction type 9191/VS-03 for single-channel versions and
Type 9191/VS-04 for two-channel versions.
• Guide the compensation line of the thermocouple to the reference junction.
