The analogue input module UR20-4AI-RTD-DIAG can detect
up to 4analogue resistance thermometers. The resolution is
16bit per channel. A sensor can be connected to each con-
nector in a 2-wire, 3-wire or 4-wire connection. Mixed opera-
tion using different sensors as well as different connection
methods is possible. Sensor type and temperature range are
set using parameterisation. A status LED is assigned to each
channel.
The inputs are protected against voltage surges and overcur-
rent. Voltages that exceed ±30V may cause the destruction
of the module.
The module provides individual channel diagnosis with chan-
nel related error messages.
