FAQ for TRICONEX 3101
Q1: Does 3101 support AC digital input signals?
A1: This standard 3101 model is designed for 24 V DC digital signals. AC input needs to select other corresponding Tricon digital input models.
Q2: Can 3101 work without a Tricon main processor?
A2: No. It must be installed in the Tricon rack and communicate with main processor via the proprietary backplane bus.
Q3: What will happen if one channel of 3101 fails?
A3: The TMR voting algorithm masks the single channel fault, the module continues working and the system reports the fault alarm for maintenance.
