Digital Output Module with Rotary Switch

The digital output module can be used to output six events. These events can be warnings or trips and can be used for external annunciation or control. A circuit breaker trip can be wired to an Alarm Horn or Stack Light.

The load shedding and load restoring signals can enable a load to be switched ON or OFF automatically depending on the load.

The digital output module is available in two versions. The "optocoupler" version features solid state outputs. The current carrying capacity of this output is 150mA, and the nominal voltage is 24V DC. Only DC voltage can be switched. The "relay" version, uses a relay contact with a maximum load of 12A. Voltages of up 250V AC/DC are possible. The relay contacts are isolated.

The module is configured using a rotary switch, which not only selects one of the two output module versions, but also sets the appropriate delay time.

Selector switch position to the left

If the rotary switch is positioned to the left, outputs 1 through 6 are assigned the following events:

•Output 1: Long-time trip (L)

•Output 2: Short-time trip (S)

•Output 3: Instantaneous trip (I)

•Output 4: Ground fault trip (G)

•Output 5: Ground fault alarm signal

•Output 6: Trip as a result of overload in the neutral conductor

(N)

Selector switch position to the right

If the rotary switch is positioned to the right, the 6 outputs are automatically assigned the following functions:

•Output 1: Leading overload trip signal (delay time 0s)

•Output 2: Trip unit error (ETU)

•Output 3: Load shedding

•Output 4: Load restoring

•Output 5: Temperature alarm

•Output 6: Current phase unbalance

Delay time

The rotary switch can also be used to set an additional delay time. Available times are 0, 0.2 s, 0.5 s, 1 s, and 2 s.

These can be used, for example, to suppress events that only last a short time and not output them until they have been present for a long period (e.g. phase unbalance).

Irrespective of the delay time that has been set, the signal for the leading overload trip, which can be used to switch off and protect connected frequency converters, is always instantaneous.

A maximum of two digital output modules with rotary switches can be operated simultaneously on one WL Circuit Breaker, otherwise erroneous outputs may occur. They must be configured opposite each other. One in the operating mode with the switch position to the left and one with the switch position

to the right.

The LEDs display the current state of the 6 outputs. If the LED is OFF, the corresponding output is OFF. If the LED is yellow, the output is ON.
