## Abstract

The disclosure relates to a safety module for an automation system assembly, having a safety component which is configured to implement a safe operation of the automation system assembly, and an adaptation component which is configured to mediate between the safety component and a communication system of the automation system assembly in order to incorporate the safety module into the automation system assembly, wherein the safety component and the adaptation component are constructed on separate circuit carriers and are connected in such a way that they are mechanically detachable and reconnectable.

## Claims

### Claim 1

A safety module for an automation system assembly, the safety module comprising:
a safety component configured to implement a safe operation of the automation system assembly; and
an adaptation component configured to mediate between the safety component and a communication system of the automation system assembly to incorporate the safety module into the automation system assembly,
wherein the safety component and the adaptation component are constructed on separate circuit carriers and are connected so as to be mechanically detachable and reconnectable.

### Claim 2 (depends on 1)

The safety module according to claim 1, wherein the safety component is a certified component and the adaptation component is a non-certified component.

### Claim 3 (depends on 1)

The safety module according to claim 1, wherein the communication system of the automation system assembly is a bus system and the adaptation component is configured to mediate between the safety component and the bus system.

### Claim 4 (depends on 1)

The safety module according to claim 1, wherein the safety component and the adaptation component have a communication connection to one another via an internal communication system.

### Claim 5 (depends on 4)

The safety module according to claim 4, wherein the adaptation component is configured to mediate between the internal communication system and the communication system of the automation system assembly.

### Claim 6 (depends on 1)

The safety module according to claim 1, wherein the safety component has a safety logic and the adaptation component has an adaptation logic.

### Claim 7 (depends on 1)

The safety module according to claim 1, wherein the safety component and the adaptation component in each case have their own printed circuit boards.

### Claim 8 (depends on 1)

The safety module according to claim 1, wherein the adaptation component has a device configured to implement overvoltage protection.

### Claim 9 (depends on 1)

The safety module according to claim 1, wherein the adaptation component has a voltage limitation for the safety component.

### Claim 10 (depends on 1)

The safety module according to claim 1, wherein the adaptation component has a voltage converter.

### Claim 11

An automation system assembly, in particular a safety control or safe drive, comprising:
a communication system; and
a safety module comprising:
a safety component configured to implement a safe operation of the automation system assembly; and
an adaptation component configured to mediate between the safety component and the communication system of the automation system assembly to incorporate the safety module into the automation system assembly,
wherein the safety component and the adaptation component are constructed on separate circuit carriers and are connected so as to be mechanically detachable and reconnectable.

### Claim 12 (depends on 11)

The automation system assembly according to claim 11, wherein the automation system assembly is one of a safety control and safe drive.

### Claim 13 (depends on 3)

A safety module according to claim 3, wherein the bus system is a host bus system.

### Claim 14 (depends on 4)

The safety module according to claim 4, wherein the internal communication system is an internal bus system.

### Claim 15 (depends on 9)
