Setting Up the Hardware

This chapter helps you install the hardware with these tasks:

• connect the LDT to module input terminals

• connect module output terminals to output devices

• minimize interference from radiated electrical noise

• considerations for the "15V dc power supply

• other design considerations

We assume that you will use one of the following types of LDT:

• Temposonics II: RPM TTSRxxxxxxR, or

DPM TTSRxxxxxxDExxx

• Balluff: BTL-2-L2, or BTL-2-M2

• Santest: GYRP, or GYRG

• Gemco Quick-Stick II: 951VP, or 951 RS

We illustrate typical connections between the 1746-QV module and

these types of LDTs. (There are other suppliers with compatible LDTs.)

Note 1: In the table, we use the term “gate out” for pulse trigger or square wave (Gemco) and start/stop (Balluff -M2) LDT signals.
