Neptronic SHS80-300 Humidistat
The Neptronic SHS80-300 serves as a high-precision duct mount humidity high limit switch, engineered specifically for monitoring and controlling relative humidity in supply or return air ducts. This dual-function device operates as a 0-10 Vdc humidity transmitter while providing critical on/off high-limit protection for modulating humidifiers. Designed with a robust ABS plastic enclosure, it features an on-board setpoint adjustment range of 20% to 90% RH. Technical accuracy is maintained through a sensor precision of ±3% at 40% RH, ensuring reliable integration with Neptronic SKR, SK300, and SKE series units. The 24 Vac/Vdc power supply requirement and dry contact rating of 1A at 24 Vac make it a versatile component for commercial HVAC configurations. Dual LEDs provide immediate visual diagnostics, indicating power status and high-limit cutout activation. For field technicians, the 18 AWG minimum wiring and standard duct-mount footprint facilitate efficient installation and long-term system stability.
Key Benefit List
- Dual-Function Performance: Integrates a 0-10 Vdc humidity transmitter with an independent high-limit cutout for streamlined control.
- Precise Setpoint Control: Features a wide humidity setpoint range of 20% to 90% RH with convenient on-board adjustment.
- Visual Diagnostics: Built-in LEDs allow for rapid troubleshooting of power status and alarm conditions in the field.
- Universal Compatibility: Optimized for seamless integration with Neptronic humidifiers and standard 24V control circuits.
- Durable Construction: Built with a high-grade duct mount humidity sensor housing suitable for operating temperatures up to 140°F.
Common Questions
How do I wire the SHS80-300 for high-limit protection?
The unit utilizes two dedicated terminals for the dry contact high-limit switch. These should be wired in series with the humidifier's safety circuit or external enable input to ensure the system shuts down if the duct humidity exceeds the setpoint.
Can this sensor be used for return air sensing?
Yes, the SHS80-300 is designed for installation in either the supply or return air duct. When used in the return duct, it provides accurate feedback for space humidity levels via the 0-10 Vdc output.
What is the humidity sensing accuracy of this model?
The internal humidity transmitter provides an accuracy of ±3% RH at standard operating conditions, ensuring precise modulation of the humidification equipment.
