Kromschroder Actuator IC40A2A 88300088

The Kromschroder IC40A2A actuator (SKU 88300088) is a high-precision rotary motion device designed for accurate control of gas and air volume in burners and boilers. It operates with a 4–20 mA analogue input, has a runtime of 6 seconds, and provides a torque of 2 Nm. The actuator is programmable via an optical interface using BCSoft software, with parameter set 68001 and operating mode 06. It features a duty cycle of 100%, protection class IP65, safety class 1, and operates within a frequency range of 50–60 Hz. The device weighs 2000 g and includes digital outputs rated at 2 A, with a holding torque equal to its torque. It is equipped with three M20 plastic cable glands and accepts cables up to 4 mm² (single core) or 2.5 mm² with ferrules. The actuator is suitable for use with butterfly valves achieving a control ratio of 10:1 and with VFC valves achieving 25:1. Its storage temperature range is -20 to 40 °C, and condensation must not be permitted.

When selecting an actuator of this type, ensure the torque, runtime, and control signal (e.g., 4–20 mA) match the application requirements. Verify the mounting dimensions and shaft coupling compatibility with the valve or damper. The actuator must be installed in a location that meets the specified ambient temperature and protection class (IP65). Electrical connections should be made with cables of appropriate cross-section, and the line entrance must accommodate the cable glands. Programming and parameter settings must be configured to match the control system.

Common failures of such actuators include loss of positioning accuracy, erratic movement, or complete failure to operate. This may be due to electrical issues, such as damaged cables or connectors, or mechanical wear in the gear train. If the actuator does not respond to control signals, check the power supply, signal wiring, and programming. Overheating or condensation can cause internal damage, leading to intermittent operation. Regular inspection of the cable glands and seals is recommended to prevent moisture ingress.
