Kromschroder Actuator IC40A2D 88300085

The Kromschroder IC40A2D actuator (SKU 88300085) is a rotary actuator designed for precise and controlled movement from 0° to 90°. It operates with a torque of 2 Nm and a runtime of 6 seconds, suitable for adjusting gas and air volumes in various appliances and flue gas lines. The actuator features a 4–20 mA analogue input, two digital outputs as relay change-over contacts, and is programmable via an optical interface. It has a duty cycle of 100%, protection class IP65, and safety class 1, with a weight of 2000 g. The device operates at 50–60 Hz and complies with certifications 2014/35/EU, 2014/30/EU, and DIN EN 60730.

When selecting a replacement actuator of this type, ensure the torque, runtime, and mounting dimensions match the original. The actuator must be compatible with the control system's voltage and signal requirements, including the analogue input range and digital input/output specifications. Check the line entrance size and cable gland type to ensure proper electrical connection. The ambient and storage temperature ranges must be within the equipment's operating environment, and condensation must be prevented.

Common failures of this actuator type include loss of torque or holding torque, which may cause the valve or damper to drift from its set position. If the actuator fails to respond to control signals, check the digital inputs and outputs for proper voltage and current. Overheating or condensation can lead to internal component damage, resulting in erratic movement or complete failure. Inspect the cable glands and enclosure for signs of moisture ingress or physical damage.
