Comparator output

0 V

3

Power contact 0 V (internally connected to terminal point 7)

C

4

Input C or
zero input (in case bit 0 (EnLatchC) is set in the control byte, a rising edge at this input causes the current counter value to be saved in the latch register as a reference mark).

Power contact +24 V

0 V

7

Power contact 0 V (internally connected to terminal point 3)

Gate/Latch

8

Gate input or
Latch input: if

  • bit 3 (EnLatchRise) is set in the control byte, a rising edge
  • bit 4 (EnLatchFall) is set in the control byte, a falling edge

at this input causes the current counter value to be saved in the latch register as a reference mark.
