3.3 Assignment signal input

Choice of PNP or NPN The contacts 9 to 12 are comparator signal inputs.

They can be triggered either by PNP or NPN encoders. The input

logic as well as the operating threshold are correspondingly chosen

in programming line 28. The contacts 9 (Track A) and 10 (Track B) are

counting inputs for a counting range between 3 Hz, 25 Hz or 10 kHz.

The counting rate is determined in programming lines 26 and 27.

The contacts 11 and 12 are 2 control inputs for Reset, Stop, Hold,

Print, Keylock, etc. The function of these control inputs is selected in

the programming lines 29 and 31

Input resistance Selectable operating threshold

approx. 3 kΩ 2.5 V, 5 V and 10 V

3.4 Typical connections

Sensor Assignment Programming

Contact Counting rate:

9 track A Line 26 to 1 = 25 Hz

8 +24 V Line 26 to 2 = 3 Hz

Proximity switch PNP or NPN

9 track A Input logic:

8 +24 V Line 28 to 0 = PNP

7 0 V Line 28 to 1 = NPN

Namur without explosion protection

9 track A Input logic:

7 0 V Line 28 to 3 = NPN

Incremental Counting mode:

9 track A A 90º B (x1, x2, x4)

10 track B Line 25 to 3, 4, 5

8 +24 V Counting rate:
