Safety Speed Monitors

Safety Speed Monitors are used in applications where there is a high safety risk to people and machinery. It is necessary and required by law to fulfill certain safety criteria to reduce injury in these situations. The DS series Safety Speed Monitors are specifically designed for these industrial applications. These safety speed monitors are used to monitor underfrequencies, overfrequencies, direction of rotation and machine standstill. SIL3/PLe and SIL2/PLd certifications according to the DIN 61508 and ISO 13849 are standard on these safety speed monitors and the safety relays ensure maximum safety and plant availability.

Plug-in Display BG200

Short description on BG200:

The BG200 clip-on display is an optional accessory and is compatible with all DS Safety Speed Monitor models. The BG200 clip-on display is used for visualization and diagnostic purposes when there is no PC available. The BG200 can also be used to parameterize the speed monitors. Once the parameters have been saved, it can simply be transferred from one speed monitor to another speed monitor.

SIndividual scalable process or speed indicator
Dual channel frequency indicator for visualization of the encoder frequency
Display of alarm and error codes
Touch screen with intuitive menu guidance
1.54" OLED Display (128 x 64 Pixel)
