OPTO 22 – AD14T _ G1 10 Ohm RTD Analog Input, Isolated
Quick Specs:
- G1 10 Ohm RTD Analog Input
- Isolated
G1 I/O family
The AD14T is a 10 ohm copper RTD analog input with a nominal temperature range of -55 °C to 150 °C (-67 °F to 302 °F). This module provides a single channel of optically isolated RTD temperature-to-digital conversion with 4,000 Vrms of transient isolation.
This module is suitable for temperature measurements where the RTD probe is grounded or when ground loop currents exist.
