E16225D

Single Channel Monitor series E16225D for measurement of speed + detection of direction with fault indication for increased safety requirements up to SIL2

The BRAUN Single Channel Speed and Direction Monitor E16225D for increased safety requirements is SIL2 / IEC 61508:2010 compliant. It simultaneously measures one speed value and the direction of speed with fault indication. The signal input is specially designed for our proven Differential-Hall-Effect-based A5S speed sensors. Either with speed and direction signal (A5S…3) or two-phase shifted speed signals (A5S…4).

Display, setpoints, and analog output may be adjusted to any speed. During its complete useful lifetime of 20 years, the Monitor does not require any external proof tests and is completely maintenance-free.
