1794-OE4XT is installed with FLEX I/O adapter and backplane, 1794-TB2, TB3, TB3S, TB3T, TB3TS or TBN base, 24 V DC external field supply, compatible analog actuators or reference inputs.
Engineered applications include Valve-positioner command outputs, Variable-speed drive reference signals, Process setpoint generation, FLEX I/O analog-output modernization.
Important Notice: Isolate the FLEX I/O station and field supply, key the terminal base to position 4, preserve channel polarity and commons, then validate each output at low, midpoint and high command values.
