• 4 to 20mA DC input
• 4 to 20mA DC output
• 12-50V DC power from output loop
• Low cost isolator

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.

For easy troubleshooting, each unit has LEDs and diagnostic test points. Power LEDs help identify output open loop conditions. The precision 10 ohm sense resistor enables monitoring of the output signal without disturbing field wiring.

Power Requirement
12 to 36V DC (loop-powered)
Two-wire transmitter

Approvals
CE marked. UL, cUL listed
Class I, Division 2, Groups A, B, C, D.

Features

• Two channels in 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.
• Power LEDs provide a visual indication of operational process loops.
• Excellent accuracy and stability ensure reliable operation in noisy environments.
• Operating temperature range: -25 to 70°C (-13 to 158F).
