HI
= High, positive pole
LO
= Low, negative pole
F
= Force
S
= Sense
GND = Ground, pin 9
The "HI_F", "HI_S", "LO-F" and "LO-S" lines have identical electrical properties.
There are 6 switching positions (n = 1...6), in which the four coupled SP6T relays can
be switched synchronously to connect their common terminals to one of their n output
pins:
Figure 3-38: Here, all switches (K1 to K4) are in position 1 of 6
The 6 positions result in the following connections:
●
Position 1:
–
Signal at "HI_F" INPUT pins 1 & 2 is switched to "HI_F1" (pin 1) of OUT1/2
–
Signal at "HI_S" INPUT pins 3 & 4 is switched to "HI_S1" (pin 2) of OUT1/2
–
Signal at "LO_F" INPUT pins 5 & 6 is switched to "LO_F1" (pin 3) of OUT1/2
–
Signal at "LO_S" INPUT pins 7 & 8 is switched to "LO_S1" (pin 4) of OUT1/2
●
Position 2:
–
Signal at "HI_F" INPUT pins 1 & 2 is switched to "HI_F2" (pin 5) of OUT1/2
–
Signal at "HI_S" INPUT pins 3 & 4 is switched to "HI_S2" (pin 6) of OUT1/2
–
Signal at "LO_F" INPUT pins 5 & 6 is switched to "LO_F2" (pin 7) of OUT1/2
–
Signal at "LO_S" INPUT pins 7 & 8 is switched to "LO_S2" (pin 8) of OUT1/2
●
Position 3:
–
Signal at "HI_F" INPUT pins 1 & 2 is switched to "HI_F3" (pin 1) of OUT3/4
–
Signal at "HI_S" INPUT pins 3 & 4 is switched to "HI_S3" (pin 2) of OUT3/4
–
Signal at "LO_F" INPUT pins 5 & 6 is switched to "LO_F3" (pin 3) of OUT3/4
–
Signal at "LO_S" INPUT pins 7 & 8 is switched to "LO_S3" (pin 4) of OUT3/4
