Belimo P140A - feedback potentiometer

Belimo P140A feedback potentiometer

The P140A is a clip-on feedback potentiometer for damper actuators and rotary actuators. The mounting plate transfers the position from the damper actuator shaft clamp or the rotary actuator position indicator to the potentiometer.

Key features and specifications

• Nominal resistance: 140 Ω; tolerance: ±5%.
• Maximum load: 1 W; linearity: ±2%; resolution: min. 1%.
• Residual resistance: max. 5% on both sides.
• Potentiometer connection: 1 m cable, 3 x 0.75 mm², FRNC (halogen-free).
• Degree of protection IEC/EN: IP54; protection class IEC/EN: III, Safety Extra-Low Voltage (SELV).
• Ambient temperature: -30...50°C [-22...122°F].
• Weight: 0.18 kg.

The potentiometer is designed for modulating damper control in combination with controllers with fixed feedback. It can also be used with commercially available damper position indication systems or as a setpoint device for actuators operating in parallel. It is mounted directly on the damper actuator shaft clamp or on the rotary actuator position indicator.
