Application & Failure Scenarios
The module receives thermocouple and millivolt signals used in process measurement. During maintenance, it may be searched for when multiple temperature readings are lost, input values become abnormal, or a channel no longer provides reliable measurement data. An unresolved input failure can reduce process visibility and delay operating decisions, potentially affecting production continuity. Check field sensors, wiring and the associated control-system channel before replacing the module.
