633T, 4 Yollu AC/DC-Poweres 4-20mA Splitter

Signal Splitter, AC/DC-Powered

• One 4 to 20mA DC input
• Two 4 to 20mA DC outputs
• 15-36V 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.



  • Two channels in a single unit saves space and reduces costs.
  • Signal splitter model provides two identical isolated outputs from one input signal.
  • Built-in isolated excitation supply with short circuit protection can drive up to two field 2-wire process loops.
  • Full isolation safely separates each input channel, each output channel, the excitation supply, and power.
  • Excellent accuracy and stability ensure reliable operation in hostile environments.
  • Low input burden keeps voltage drop to less than 1.5V for full-scale current.
  • Supports wide 0 to 1000 ohm load range and no trimming is required if the load varies.
  • Current limiting safely limits output to 27mA.
  • Pluggable terminals, zero/span trim pots and power LEDs make installation, maintainance, and long term service easy.
  • -25 to 75°C (-13 to 167°F) operation, [if excitation supplies are used on 633T -25 to 60°C (-13 to 140°F)]
