Speed Monitor
SAFEONE DN3PD2
Our SAFEONE DN3PD2 module is suitable for safe speed monitoring of electrical drives in plant and machinery. Neither proximity switches nor incremental encoders are required for monitoring (measuring the operating status). The module is configured using our GO:BEYOND Software and meets Performance Level e according to DIN EN ISO 13849-1.
