For electromechanical thrust and positioning drives for protecting the mechanism from collision-related overloads. Especially as an accessory for RACO's electric actuators with the DIR / DIG Pulse generator  

Monitors the motor speed and switches off the actuator  when it reaches a set maximum speed and / or  it falls below the set minimum speed. The restart block is set back as soon as the drive has received the actuating command in the opposite direction.

• speed monitoring from 1 ...... 60 000 rpM

• diverse pulse evaluation system

• actual value display/operating point programming in Hz or UPM digital

• 2 switching points can be programmed

• scalable from 4 to 20 mA with analog output

• additional functions such as start-up bridging and switch delay time, impulse time and storage function can be individually programmed
