Conversion Module Installation and Application Considerations
The 1771-OBN module output current limits versus 1756-OB32 limits are as follows:
1771-OBN
1756-OB32w/1492-CONCAB005Z
a) Current/Point
0.5A
0.35A @ 60˚C
b) Current/Module
8A
6A @ 60˚C
c) Surge Current/Point
2A for 10ms
1A for 10ms
The 1771-OBN has four (4) 4A, 250V rectifier fuses. The 1756-OB32 is NOT fused, as such four (4) 2AG fuse clips and 4A
fuses are provided on the 1492-CM1771-LD009F conversion module.
The 1492-CONAB005Z is limited to 3A per pin.
The 1771-OBN has 4 groups (allowing 4 separate power supplies) and the 1756-OB32 has 2 groups. This module/cable
combination ties Groups 0 & 1 from the 1771-OBN to Group 0 on the 1756-OB32 and Groups 2 & 3 from the 1771-OBN to
Group 1 on the 1756-OB32. Field wiring modification must be made to accommodate this if multiple supplies were used.
If 4 supplies were used, 2 must be removed.
Refer to your 1771-OBN and 1756-OB32 Installation Manual wiring schematics and diagrams for more details. Ensure
1756 output module ratings are not exceeded.

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.
