Kromschroder Servomotor IC20-07W2E 88300074

The Kromschroder IC20-07W2E (SKU 88300074) is a continuous control actuator designed for precise rotary movement from 0 to 90 degrees. It operates on a 230 V supply at 50–60 Hz, delivers 2 Nm torque, and has a 100% duty cycle. The actuator features voltage-free limit switches and a feedback potentiometer rated at 0.5 W. It is certified to 2014/35/EU, 2014/30/EU, and DIN EN 60730-1, with a safety class of 1. The device weighs 1950 g and is suitable for regulating gas and air volumes in various applications.

When selecting an actuator of this type, ensure the supply voltage, frequency, torque, and control signal match the system requirements. The mounting dimensions and shaft coupling must be compatible with the driven element. The actuator's angle of rotation and limit switch settings should be adjustable to match the valve or damper travel. Electrical connections are made via screw terminals, and cable glands must accommodate the required cable cross-section.

Common failures include loss of positioning accuracy, erratic movement, or complete stoppage. This may be due to worn gears, faulty limit switches, or a damaged feedback potentiometer. Check for loose wiring, condensation, or overheating, which can cause intermittent operation. If the actuator halts unexpectedly, verify the power supply and control signal integrity.
