AI830A
AI830A Analog input RTD 8 ch
Overview
Description
The AI830/AI830A RTD Input Module has 8 channels for measurement of temperature with resistive elements (RTDs). With 3-wire connections. All the RTDs must be isolated from ground.
Key Benefits
- 8 channels for RTD (Pt100, Cu10, Ni100 and Ni120 and resistor) inputs
- 3-wire connection to RTDs
- 14 Bit resolution
- Inputs are monitored for open-circuit, shortcircuit and has a input grounded sensor
Specifications

Variant
- Isolation
- Groupwise isolated from ground
- Error
- Error dependent of the field cable resistance: Rerr = R* (0.005 + ∆R/100) Terr°C = Rerr / (R0 * TCR) Terr°F = Terr°C * 1.8
- Temperature drift
- See table in S800 Modules and Termination Units, 3BSE020924-xxx
