OPTB8 accuracy
The following table represents the results of accuracy measurements in laboratory environment. In
the tests we used Draga JAMAK cable. The testing covered different sensor setups.
NOTE: Because of accuracy reasons OPTBH is recommended for newer installations. Please note
that using of OPTBH requires support from NX application.
Connection of PT100 sensors
One PT100-sensor can be connected to the first two inputs (terminals 1 to 3 and 4 to 6) and up to
three sensors to the third input (terminals 7 to 9). The sensors must be connected in series with a
two- or three-wire connection. See Chapter Jumper selections below.
NOTE:
• This expander board can be placed into four different slots on the control board. Therefore,
the 'X' given in the Parameter reference must be replaced by the slot letter (B, C, D, or E)
depending on the slot which the expander board is plugged into. See chapter 1.7.
• Insulation level 4kV/sqrt(2) (DIN VDE 01 10-1). 2kV in sensor and 2kV in option board.
