6-3-4 For Output connection
Since the transistor output is insulated from the internal circuit by a photo-coupler, it can be used both
as a NPN output and PNP (equal value) output.
6-3-5 For Wiring terminal
・
When using a crimp terminal, it should be with insulation sleeve applicable to M3.5 screw as shown
below.
・
Tightening torque: under 0.8N

6-3-6 RS-485 communication
・
When using shielded cable for the RS-485 transmission line, ground one end. Use a class D (class 3)
dedicated earth for grounding. Do not share a ground with other earth lines. (Fig.1)
・
Change the slide switch on the side of main unit as a terminal station. (Fig.2)
・
Be sure to connect with daisy chain the RS-485 transmission line between each unit.
Do not use a splitter. (Fig.3)
