    633T: AC/DC-Powered Signal Splitter

    • Single input, dual output (splitter)
    • 12-36V DC SELV, 90-250V AC
    • Provides two identical outputs from one input signal
    These units receive 4-20mA process current inputs and provide isolated 4-20mA output signals. Each channel operates independently and is isolated from the others to prevent interaction between channels. Galvanic isolation eliminates ground loops, reduces noise, and blocks transient signals.
