Instructions to connect the TP47 connector for Pt100 probes or Pt1000
All Delta Ohm probes are provided with a connector. The HD2205.2, HD2206.2 and HD2256.2 in-
struments also work with direct 4 wire Pt100, and 2 wire Pt1000 probes manufactured by other pro-
ducers: For the instrument connection is prescribed the TP47 connector to which the probe's wires
should be welded.
The instructions to connect the Platinum probe to the TP47 module are provided below.
The module is supplied complete with fairlead and gasket for 5mm maximum diameter cables.
Do the following to open the module and connect a probe:
Unscrew the fairlead and extract the gasket, remove the label using a cutter, unscrew the ring on the
opposite side as illustrated in the figure:
Open the two module shells: The printed circuit to which the probe must be connected is housed in-
side. On the left there are the 1…4 points on which the sensor wires must be welded. The JP1…JP4
jumpers are in the center of the card. These must be closed with a tin bead for some type of sensors:
