1. All terminals marked RTN are connected internally.

2. A 249

W current loop resistor is located between IN-x and i RTN-x terminals.

3. For current applications, all terminals marked i RTN must be wired to terminals

marked RTN.

4. Place additional loop devices (e.g. strip chart recorders, etc.) at either A location.

5. If separate power sources are used, do not exceed the specified isolation voltage.

6. Do not connect more than 2 wires to any single terminal.
