REE-2002

Connections and Wiring

1. Connect a controller input to one of the three

THE-1102/REE-2002 (0–5 VDC, 0–10 VDC, 4–20 mA) outputs as shown in the sample illustration below.

2. Connect the B, F, C, and D terminals to the corresponding terminals on the THE-1102.

3. Supply the REE-2002 with 24 VAC (+20%/–15%) from a Class 2 transformer (only).
