The analogue input module UR20-4AI-TC-DIAG can detect
up to 4analogue thermocouple sensors or voltages between
± 15mV and ± 2V. The resolution is 16bit per channel. Sen-
sor type and temperature range are set using parameterisa-
tion. Mixed operation using different sensors is possible. For
each channel, an internal or external cold-junction compen-
sation (CJC) can be parameterized. 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.
