ac/dc (120V) Isolated Input Module 10
Publication 1771-IN070B-EN-P - August 2002
IMPORTANT
You can use an ac (120V) output module (cat.
no. 1771-OA, 1771-OD or 1771-OP) to directly
drive terminals on an ac/dc (120V) input module
(cat. no. 1771-ID16), but you must use a 2.5K,
10W resistor between the output terminal and
L2 (common) as shown in the following figure.
