Belimo S2A Auxiliary Switch

The Belimo S2A auxiliary switch is engineered for precise position signaling and versatile switching functions within HVACR systems. This robust add-on unit features a 2x SPDT (Single Pole Double Throw) configuration, providing reliable feedback for damper and rotary actuators. With a switching capacity of 3A (0.5A inductive) at 250 VAC, or 0.5A (0.2A inductive) at 110 VDC, it integrates seamlessly into various control sequences. Installation is straightforward, designed for direct mounting onto the actuator's shaft clamp or position indication, ensuring a secure fit. Technicians can easily adjust the switching points across the actuator's full range of rotation (0-100%) using a simple dial, allowing for fine-tuned application control. Its NEMA 2, IP54 rated housing ensures durability in demanding environments, operating reliably in ambient temperatures from -30°C to 50°C. This damper actuator switch is a maintenance-free solution for critical system monitoring.
