The DS246 series Safety Speed Monitor is designed to be connected to a SIL3/PLe certified sine / cosine encoder or sensor.
The DS246 Safety Speed Monitor is equipped with a relay, 4 transistor outputs and an analog output, but has no signal distributor when compared to the DS240.
Safety Speed Monitors are used in applications where there is a high safety risk to people and machinery.
The DS series Safety Speed Monitors are specifically designed for these industrial applications.
