Distributor for supplying actuators and/or sensors

The invention relates to a distributor for the supply of actuators and/or sensors with connections for the actuators and/or sensors as well as electronics for the supply of the actuators and/or sensors and the forwarding of the actuator-sensor signals.

Such a distributor is known from G29905025.

10 This distributor has proven itself to be effective. However, particularly when connecting actuators, there is a need to be able to react to actuator faults in the simplest possible way.

The solution to this problem is the object of the invention.

The invention solves this problem by the subject matter of claim 1. According to this, a device for emergency actuation of the actuators and/or sensors is provided on the distributor.

Preferably, a switch is connected to at least one of the connections, which is connected to at least one further connection to which one of the actuators or sensors is connected, in such a way that a data line or a supply potential is led from the electronics to the connection for the actuators and/or sensors via the switch of the further connection, so that by opening and closing the switch this data or supply line is interrupted or closed.

The emergency operating level makes it possible, in the event of a fault, to attempt to activate the actuator or sensor simply by activating the emergency operating level once or several times, preferably by activating the switch according to claim 2. For example, an attempt can be made to "shake loose" a valve by activating the switch several times. This method will not always be successful. Experience has shown, however, that some faults, particularly with valves, can be remedied in this way.

Advantageous embodiments of the invention can be found in the subclaims.

An embodiment is described in more detail below with reference to the figure. It shows:

Fig. 1 is a schematic view of a distributor according to the invention; and Fig. 2 is a sketch of the wiring of two connections of the distributor.

Fig. 1 shows a distributor, to whose housing part 2, which is provided with electronics, data lines from and to a control device (not shown here) can be connected.

This housing part 2 is either formed in one piece with a housing part 3 or can be attached to and detached from it. The housing part 3 is provided with eight connections 4a, 4b, ... for connecting the actuators and/or sensors. 5

The connections 4 are each designed with five poles, for example. A pushbutton switch 5 with connection legs molded onto it can be plugged into one of the connections 4a. This connection 4a is connected or wired to another connection 4b in the manner shown in Fig. 2, in such a way that a line 6, in particular a data line or a supply potential to the connection 4b for the actuators and/or sensors, is led via the switch of the other connection 4a, so that this data or supply line is interrupted or closed by opening and closing the switch.

In this way, an attempt can be made to "shake loose" a valve 5 connected to connection 4b in the event of a fault.

Replaceable electronics allow for a high degree of flexibility in the interconnection of the connections, since the actual interconnection of the connections takes place in or via the electronics.

Claims (6)

1. Distributor for supplying the actuators and/or sensors with connections for the actuators and/or sensors as well as electronics for supplying the actuators and/or sensors and forwarding the actuator-sensor signals, characterized in that a device (S) for emergency actuation of the actuators and/or sensors is provided on the distributor ( 1 ). 2. Distributor according to claim 1, characterized in that a switch ( 5 ) is connected to at least one of the connections ( 4a ), which switch is connected to at least one further connection ( 4b ) to which one of the actuators (S) or sensors is connected, in such a way that a line ( 6 ) is led to the connection ( 4b ) for the actuators and/or sensors via the switch ( 4a ) of the further connection ( 4a ). 3. Distributor according to claim 1 or 2, characterized in that all connections ( 4 ) of the distributor are connected together in pairs. 4. Distributor according to one of the preceding claims, characterized in that the switch ( 5 ) is designed as a switch which can be plugged directly into the terminals ( 4 ) designed as connection sockets. 5. Distributor according to one of the preceding claims, characterized in that the switch ( 5 ) is designed as a push-button switch. 6. Distributor according to one of the preceding claims, characterized in that the interconnection of the connections is formed in a replaceable electronic module of the distributor ( 1 ).
