Key issues

Question: What are the core positioning differences between PNOZmulti Classic and Mini, and what scenarios are they suitable for?

Answer: Classic is a standard modular safety controller that supports complete expansion and specialized models (press/burner), suitable for medium to large equipment with ≥ 4 safety functions; Mini is a compact device with small size and limited expansion, suitable for small devices with ≥ 3 safety functions and distributed safety points.

Question: How does this series of controllers achieve the highest level of safety? What are the safety levels for single and dual channel input and output?

Answer: By relying on dual MCU redundancy, hardware self-monitoring, and output short circuit monitoring, the highest safety can be achieved. Single channel input/output can reach PL d/Cat.2/SIL CL 2; Dual channel can achieve PL e/Cat.4/SIL CL 3.

Question: How is the system response time calculated? What is the maximum response time for Classic basic unit+semiconductor output as an example?

Answer: Total response time=maximum input delay+maximum output shutdown delay. The input delay of the Classic basic unit is 4ms+the semiconductor output is turned off for 30ms, totaling a maximum of 34ms.
