Key Features:

These transmitters isolate and convert sensor inputs to noise-free, proportional DC current or voltage output signals In addition they are equipped with an optional relay output adds a local limit alarm function.

• High-resolution Sigma-Delta A/D converter delivers high accuracy with low noise.
• Advanced microcontroller provides intelligent signal processing power for
linearization,averaging, and square root computations.
• Windows XP/Vista/7 software configuration speeds setup and replacement.
• Multi-purpose inputs and outputs reduce spare stock requirements.
• Relay output option provides local limit alarm capability.
• Operating temperature range: -25 to 70°C (-13 to 158°F).
• Learn more about the 811T by choosing videos in the resource box to the right.
• All IntelliPacks require initial software configuration (order 800C-SIP).
