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.
