UO-EM-EGS4 / UO-EM-EGS41 SIL 2
Speed switch module
Short info: Universal encoder systems
- Monitor overspeeds and underspeeds
- Relay contacts / switching outputs: 2 programmable, 1 diagnostics
- Switching capacity up to 250 V AC/DC and 0.5 A
- Options: SIL 2 / PL d certification (UO-EM-EGS41)
U-ONE Generation I - speed switch module
The speed switch modules are electronic overspeed switches that monitor the defined speeds for overspeed and underspeed. By design they include a switching delay, an inverse direction of rotation evaluation, a direction of rotation dependent switching function and the option to perform a switch test. They are easily programmed via the decoder interface.
