Electromagnetic Compatibility and Electrical Safety

PM858/TP830 complies with EMC Directive EMCD 2004/108/EC technical specifications.

Performance Data

The performance of the PM858 control unit is approximately 0.5 times that of the PM862 controller. When configured redundantly, the execution performance is slightly slower than in non-redundant configurations. The redundant controller switch-over time is generally less than 10ms.
