Most important features:
IQM-s are suitable for modulating control duty up to 1200 starts per hour
IQM series have a self-breaking facility as standard , if the actuator and valve performance prove to be excessive for accurate control then brake can be enabled.
By Mechanical brake, motor heating increase and number of starts might shall be reduced in order to avoid thermostat strip.

Toughened glass screen plus optional environmental shield
Setting Tool for secured Bluetooth connection
Solid state relay for high accurate remote feedback and modulating duty
(multi-turn actuators only)
Reduced inner wiring and connection points
Torque Sensor by simplified design (mult-turn variants)
Simplified absolute position encoder by robust design and by reliable high accuracy
New cartridge style (can be separated) for multi-turn variants
