We recommend that shielded cables be used. The shielding is connected on one side, as close as possible to the terminal. Preferably, use terminal ABE-7BV10 or ABE-7BV20 to connect the shielding.
NOTE: For use with TELEFAST, reference number ABE-7CPA12, the terminal block detection strap is built in as standard in the TELEFAST.
Internal cold junction compensation:
is performed in the TELEFAST by a temperature probe (silicon).
If this compensation mode is chosen, no specific wiring has to be performed. Simply connect the TELEFAST to the module using lead TSX CAP 030. In this case, the 16 channels can be wired as thermocouples.
External cold junction compensation using an external Pt 100 probe:
when connecting directly to the SUB-D connectors, it is the user's responsibility to connect a Pt 100 probe (4 wires) to measure the terminal block temperature. In this case, the "external cold junction compensation" mode must be selected and channels 0 and 8 dedicated to this measurement. Channel 0 delivers the current to the Pt100 probe, and channel 8 performs the high impedance measurement.
In this case, only 14 thermocouple channels can be wired. The wiring should be carried out as follows:
