I wonder whether or not there is any PLC/RTU who can interface to hall effect current transformers (5 Vrms signal ) directly without any
transducers.

The hall effect Ct is quite common but I can't locate one PLC/RTU which can interface to them directly to cut cost. There are some analog IO modules can interface to 110 Vrms singal though. But its range is far beyond 5 V.

Any information will be appreciated.

GE Fanuc makes a power transducer module for the 90-30 PLC that allows direct connection to CTs and PTs. The part number is IC693PTM100. The manual for it (GFK-1734) is available on their website. The URL is www.gefanuc.com
