Liebert 4C13121G6S Board

The Liebert 4C13121G6S Temperature & Humidity Sensor Board is a critical precision monitoring component designed for integration with Vertiv Liebert thermal management systems. As a veteran-grade replacement for the 4C13121G4S, this board provides the high-fidelity environmental data necessary for data center climate control and mission-critical HVACR stability. By delivering real-time sensing to the main control logic, it ensures accurate calculation of sensible and latent cooling loads, preventing equipment overheating and moisture-related failures in sensitive electronic environments.

This OEM sensor board is engineered to withstand the continuous operational demands of precision cooling units like the Challenger 3000 and DS series. It facilitates seamless environmental monitoring by relaying precise atmospheric feedback to the system's processor, allowing for instantaneous adjustments to fan speeds and compressor staging. For contractors maintaining critical infrastructure, using this authentic Liebert replacement part is essential to maintain system calibration and ensure high-efficiency thermal management without the communication errors often associated with generic alternatives.

• Ensures accurate Liebert temperature and humidity sensor calibration for precise environmental regulation.
• Direct 4C13121G6S factory replacement ensures plug-and-play compatibility with existing Vertiv monitoring systems.
• Minimizes downtime by providing reliable telemetry to the primary HVAC control board.
• Optimizes energy efficiency by preventing unnecessary cooling or dehumidification cycles.
• Industrial-grade build quality designed for 24/7 service in server rooms and laboratories.

Is the 4C13121G6S compatible with older Liebert units?
Yes, this board is the direct factory-authorized replacement for the earlier 4C13121G4S model and is compatible with most Liebert precision cooling frames requiring a dedicated sensor interface.

Do I need to recalibrate the system after installing this sensor board?
While the board is calibrated at the factory, it is a professional best practice to verify readings against a NIST-certified handheld hygrometer after installation to ensure the entire control loop is accurate.

What are the signs of a failing sensor board?
Common indicators include erratic humidity swings on the display, "Sensor Failure" alarms, or the cooling unit failing to stage correctly despite obvious changes in room conditions.
