TWI-ACI-TB: Loop-Powered Two-Wire AC-Current to 4-20mA Converter/Isolator
Function:
The TWI-ACI-TB is an isolated two wire current transmitter that provides high isolation from the
current input to the 4-20 mA output. The small package and its DIN rail mount make it easy for the
TWI-ACI-TB to be incorporated into larger control panels. There it may have applications such PLC
front end conditioning. etc.
