  • Temperature Transmitter Output Digital, 4-20mA, (clipped and capped) or 0-5V/0-10V output; accuracy ±0.5°C (±1°F) typical

*Specified accuracy with 24VDC supplied power with rising humidity. RTD/Thermistors are not compensated for internal heating of product.**Reset Rate is the time required to recover to 50% RH after exposure to 90% RH for 24 hours.***One side of transformer secondary is connected to signal common, so an Isolation transformer or dedicated power supply may be required.Shielded cabling is required for conformance to EMC standards.
