HR5S Series
Select Category 2 compliant safety relay modules for low-risk machinery.
Key Features
- Non-redundant safety system
Regarding the introduction of safety systems for low-risk machines
Until now, it was difficult to achieve Category 2 control, and even for low-risk machines, redundancy (Category 3) control was the only option.
However, with the HR5S-type safety relay module, it is easy to achieve a Category 2 configuration, allowing for cost and labor reduction during implementation.
- About performance levels
The degree of risk reduction contribution of a safety system is classified by performance level.
A Category 2 configuration (architecture) can realize control systems with PL = c or PL = d.
Please conduct a risk assessment and confirm the required performance level (PLr) for the machine.
PLr = c exists particularly in packaging machines, food machinery, semiconductor manufacturing equipment, and various other production machines and locations.
