IV. Conversion Module Wiring Diagram
The following diagrams show the connections from the existing 1771-OAD or 1771-OBD swing-arm, through the conver-
sion module, 1492 cable and to the 1756-OA16 or 1756-OB16E output module. The diagrams can be used as an aid in
possible system troubleshooting.
Conversion Module Installation and Application Considerations
The 1771-OAD module output current limits versus 1756-OA16 limits are as follows:
1771-OAD
1756-OA16 w/ 1492-CONCAB005X
a) Current/Point
2A
0.5A
b) Current/Module
8A
4A
c) Surge Current/point 25A for 100ms
5A for 43ms
The L2 terminal (Terminal E) on the 1771-OAD module was an optional connection, but it is required for the
1756-OA16. This connection must be added if it was not connected.
The 1492-CONCAB005X is limited to 3A per pin.
The 1771-OAD is rated 10V to 138V AC. The 1756-OA16 is rated 74V to 256V AC.
Refer to your 1771-OAD and 1756-OA16 Installation Manual wiring schematics and diagrams for more details.
Ensure
1756 output module ratings are not exceeded.
[Reference Doc: 41170-935 (Version 00)]
There are several key application considerations and system specifications (bottom of drawing) when
using these components (conversion module, cable and output module). Read and understand these
considerations before installation. In addition, refer to the current draw requirements of the existing
loads for this configuration to ensure they are within the current ratings of the 1756 output module.
