Products Detail:
The Z7128 module features a redundant, safety-related processor system that performs all tests directly on the module. However, external disturbances, such as pulses in the 10 Hz range (e.g., from nearby piston pumps during pressure measurements), may cause temporary channel bit faults on the analog inputs. These external pulses can negatively affect internal hardware tests, which are conducted at the same frequency, leading to fluctuations. As a result, the input channels may be incorrectly interpreted as faulty and de-energized.Z7128 Module – FAQ:
1. What is the Z7128 module?
The Z7128 is a safety-related module equipped with a redundant processor system, designed for high reliability and safety in industrial applications.
2. What is the purpose of the redundant processor system in the Z7128?
The redundant processor system ensures continuous safety and reliability by executing all tests directly on the module, minimizing the risk of failures.
3. How does the Z7128 module handle external disturbances?
External disturbances, such as pulses in the 10 Hz range (e.g., from piston pumps during pressure measurements), can temporarily affect the analog input channels. These disturbances may influence internal hardware tests and cause the input channels to be misinterpreted as faulty.
4. What happens if the input channels are misinterpreted as faulty?
If the input channels are affected by disturbances, they may be de-energized temporarily, which could impact system performance until the issue is resolved.
5. Can the Z7128 module detect and correct these faults?
The Z7128 module is designed to conduct continuous internal hardware tests, but it may still be susceptible to external disturbances. Proper shielding and system design can help minimize these issues.
