FAQ for TRICONEX 3481
Q1: What is the difference between 3481 relay module and 3201 digital output module?
A1: 3201 is solid-state 24V DC output. 3481 uses dry relay contacts which can switch different external voltage circuits.
Q2: What is the contact load limit of the relay on 3481?
A2: The relay has fixed contact power rating. Exceeding the rated current will damage relay contacts and affect safety function.
Q3: Can 3481 relay output directly drive large contactors?
A3: It is recommended to use the relay to drive a small intermediate coil, and the intermediate relay controls the large contactor.
