B200 AI02031
Analog Input Module
(2 ch., thermal)

The module is designed for measuring of signals from resistance temperature detectors and thermocouples.

Two-/three-/four-wire connection diagrams of resistance temperature detectors are supported.

It is possible to connect to the module either two resistance temperature detectors, or a thermocouple with cold junction temperature measured by an external temperature sensor (resistance temperature detector) that can be connected to any of the module channels.

• Analog input (AI module
• 2 channels
• Thermoresistances: 50M, 100M, Cu50, Cu100, 50P, 100P, Pt50, Pt100, 50H, 100H
• Thermocouples: R, S, B, J, T, E, K, N, A-1, A-2, A-3, L
• Common galvanic isolation

Compensation of cold junction temperature of thermocouples can be arranged by one of the three methods:

• Allocation of an individual channel to which a thermal resistor measuring the temperature in the cold junction point is connected
• Use of the temperature sensor integrated into the module
• Use of a preset temperature (to be preset in Sigma LD during configuration of the system)
