V. Wiring Diagrams
There are several key application considerations and system specifications (bottom of drawing) when
using these components (conversion module, cable and input module). Read and understand these
considerations before installation.
WARNING
Conversion: 1771-OAN (1) to 1756-OA16 (2)

Conversion Module Installation and Application Considerations
This Bul. 1492 cable consists of a cable wired to two 1756-OA16 RTB. Recommended cable lengths of 0.5M or 1.0M (005=0.5M,
010=1.0M). See table 2 for other lengths.
The 1771-OAN module output current limits versus 1756-OA16 limits are as follows:
1771-OAN
1756-OA16 w/ 1492-CONCAB005S3
a) Current/Point 1A
0.5A
b) Current/Module 8A (32 pts)
2A (16 pts)
c) Surge Current/Point 10A for 25ms
5A for 43ms
The 1771-OAN has 4 groups (allowing 4 separate power supplies). This module/cable combination ties all 4 groups from the 1771-OAN
together. Field wiring modification must be made to accommodate this if mulitple supplies were used. If more than 1 supply was used, all but
1 of the power supplies must be removed.
The 1771-OAN did not allow connections for L2, however the 1756-OA16 requires an L2 connection for proper operation. The 1771-OAN
did not use terminals 10, 20, 30, 40. These terminals have been reassigned for an L2 connection in this application. The installer must
rewire L2 to one of these terminals.
Refer to your 1771-OAN and 1756-OA16 Installation Manual wiring schematics and diagrams for more details. Ensure 1756 output
module ratings are not exceeded.
This configuration uses two (2) 1756-OA16 output modules to replace a single 1771-OAN output module. This may require the use of a
larger 1756 I/O chassis and conversion mounting assembly. Ensure there is sufficient panel space to allow for this possibility.
