671T / 672T / 674T:
Isolator, Single/Dual/Quad Channel

• 4 to 20mA DC input
• 4 to 20mA DC output
• Input loop powered
• Low-cost isolator
• Up to four independent channels in a single unit with channel-to-channel isolation

These units receive 4-20mA process current inputs and provide isolated 4-20mA output signals. Power is derived from the input signal current. Each channel operates independently and is isolated from the others to prevent interaction between channels.
670T

Features

  • Multiple channels on a single unit saves space and reduces costs.
  • Galvanic isolation eliminates ground loops, reduces noise, and blocks transient signals.
  • Independent channels prevent signal interaction and offer spares for later use.
  • Fault LEDs provide a clear visual warning of open or failed process loops.
  • Single calibration pot per channel enables one-step, precise calibration
  • Operating Temperature range 25 to 70°C (-13 to 158°F)
