FAQ for TRICONEX 3381
Q1: Can 3381 be used for safety shutdown valve control?
A1: It can provide modulating 4-20mA control for control valves. On-off ESD shutdown valves normally use digital output modules such as 3201.
Q2: Will 3381 output hold the last value on communication loss?
A2: The output behavior (hold last value or fail-safe) is defined by the safety logic configuration.
Q3: Is field calibration required after module replacement?
A3: After swapping the module, channel calibration verification is recommended to guarantee output accuracy.
