Overview
The Honeywell C7080A2100 is a duct-mounted temperature and humidity sensor designed for precise environmental monitoring in HVAC and building management systems. Furnished with a 20K ohm nonlinear NTC temperature sensor, this sensor delivers consistent accuracy for discharge and return air control applications. The IP54 rating provides robust protection against dust and moisture ingress, making it suitable for demanding indoor environments.
Key Features
- Nonlinear NTC20K temperature sensor with specific temperature-resistance curve
- IP54 ingress protection—dust and splash-resistant
- Designed for environmental monitoring and control in industrial, commercial and general building applications; suitable for discharge or return air control
- Duct-mounted flange installation with gasket seal
- Compatible with DDC (Direct Digital Controller) and PLC-based building automation systems
- Excellent long-term stability and linearity for HVAC applications

- Smoke management and plenum-rated duct applications
Compatibility & Replacements
Compatible With
- Honeywell Direct Digital Controllers (DDC) with resistor input modules
- Building Management System (BMS) controllers and PLCs with 4–20 mA or 0–10 VDC input conversion
- Industrial DDC systems supporting NTC sensor element input
- Standard utility conduit box and plenum-rated duct installations
Replaces / Drop-In Replacement For
Verify compatibility with your system integrator before ordering. The C7080A2100 is a temperature-only variant; do not confuse with the H7080 series, which includes integrated humidity transducers with 4–20 mA or 0–10 VDC outputs.
Works With
- Honeywell BMS and HVAC control systems
- Direct Digital Controllers (DDC) featuring NTC or resistance-input modules
- Building automation platforms supporting duct temperature feedback
- Analog resistor input cards in PLC-based systems
- Standard two-wire sensor wiring (AWG 18, AWG 20, AWG 22)
