4.9.2 TSP Terminal Strip Plates Multi-drop Wiring
These illustrations indicate the proper wiring when using TSP Terminal Strip Plates. A power supply
for each Sensor and TSP pair is shown in the first illustration. This is the preferred method.
A single power supply is shown powering three Sensors in the second illustration. A power supply
should not power more than 2 or 3 Sensors.
Use the shielded cable specified in the previous manual sections and install termination resistors as
required.
