Product Description
Schneider 5123004010 STD100-100 Duct Temp Sensor NTC 1.8K 100mm
Product Overview

The Schneider Electric 5123004010 (Model: STD100-100) is a highly reliable, passive duct temperature sensor featuring a 100mm (3.94 in.) immersion probe. This precision instrument utilizes a 1.8KΩ (at 25°C) Negative Temperature Coefficient (NTC) thermistor specifically designed to match TAC Vista, TAC Xenta, and Continuum controller standards.

As a passive sensor with no complex active electronics, it delivers accurate, drift-free air temperature measurements while providing exceptional long-term field reliability. Ideal for air temperature monitoring inside small-to-medium-sized HVAC ducts.

Technical Specifications
Protocol / Communication None. Passive resistive output.
I/O Points & Signals 1 passive resistive output channel. 2-wire non-polarized terminal block connection.
Power Supply / Voltage Passive (no external power required); drawing excitation voltage from the BAS universal input.
