FAQ for TRICONEX 3301
Q1: Can 3301 read thermocouple or RTD signals directly?
A1: No. 3301 only accepts 4–20mA signals. Temperature sensors need to connect to a temperature transmitter first.
Q2: Does 3301 support HART configuration for field instruments?
A2: It supports HART pass-through. Users can connect HART communicator to configure smart transmitters on the same loop.
Q3: If one analog channel deviates, will the safety system trip immediately?
A3: The system reports a channel mismatch alarm. The safety trip action depends on the configured voting logic and process trip setpoint.
