Description

Product Description

The Siemens 546-00437B is a 24 VAC laboratory electronic actuator intended for damper and fume hood control. It accepts floating/3-position (two 24 VAC digital inputs), 0-10 VDC, and 4-20 mA control signals and provides selectable fail-safe behavior as well as manual override. The actuator includes integral current sensing protection and offers multiple rotation angle options for integration with HVAC and lab room control systems.

  • Operates at 24 VAC; torque 97 lb-in for damper and fume hood actuation
  • Accepts floating/3-position (two 24 VAC inputs), 0-10 VDC, 4-20 mA, and Siemens pulsed signals
  • Selectable power-failure options (hold last position or fail-safe NO/NC), manual override, and integral current sensing

Product Highlights

24 VAC laboratory actuator with 97 lb-in torque, multi-input control (floating/0-10 V/4-20 mA), selectable fail-safe modes, and 45/60/90 degree rotation options
