- 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.

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

Approvals

Features & Benefits

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)
