Emergency stop and safety door monitoring

G9SA & G9SB safety relay units

To ensure the maximum required level of safety EN 954-1 defineds four categories. The highest category 4, must have redundant signal processing and failure detection. This means that the failures must not cause the loss of the safety function and the system must be able to detect failures (e.g. contact weld).
The safety relay ranges G9SA and G9SB are designed and approved for safety systems up to category 4. They are type approved and offer a wide variety of applications. They are dedicated for emergency stop monitoring, door safeguard monitoring, two hand control (G9SA-TH), safety sensor monitoring.
The G9SA range is designed to be flexible and expandable. A variety of possible combinations allows this perfect fitting safety solution. The G9SB range is designed for space critical applications and small machines.
