Conversion Module Installation and Application Considerations
This Bul. 1492 cable consists of a cable wired to one 1756-OA8E RTB. Recommended cable lengths of 0.5M or 1.0M (005=0.5M,
010=1.0M). See table 2 for other lengths.
The 1771-OA module output current limits versus 1756-OA8E limits are as follows:
1771-OA 1756-OA8E w/ 1492-CONCAB005U
a) Current/Point 1.5A 2A
b) Current/Module 6A 4A @ 60°C
c) Surge Current/Pt 4A for 8.3ms 20A for 43 ms
The 1771-OA has eight (8) 2A, 250V fuses - 1 per output. The 1756-OA8E is electronically fused per point. Refer to the 1756-
OA8E Installation Manual for details on electronic fusing.
Refer to your 1771-OA and 1756-OA8E Installation Manual wiring schematics and diagrams for more details. Ensure 1756 output
module ratings are not exceeded. [Reference Doc: 41170-943 (Version 01)]
