Wiring of a counter
You integrate a counter into your circuit in the form of a
contact and coil. The counter relay has different coils.
h
To prevent unpredictable switching states, use each coil of
a relay once only in the circuit diagram.
Do not use the input of a high-speed counter as a contact
in the circuit diagram. If the counter frequency is too high
only a random input value will be used in the circuit
diagram.

In the parameter display of a counter relay you change the
mode, the setpoint and the enable of the parameter display.

• Mode N: up/down counter
• Mode H: high-speed up/down counter
• Mode F: frequency counter

The contact switches if the
actual value is greater than or
equal to the setpoint.

Counting direction
• Coil not triggered: up
counting.
• Coil triggered: down
counting.
Reset, coil triggered: actual
value reset to 00000
