Rockwell Automation 1492-CM1771-LD006 Field Conversion Module - Manual (Page 6)

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.

Conversion Module Installation and Application Considerations
This Bul. 1492 cable consists of a cable wired to one 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-OBD module output current limits versus 1756-OB16E limits are as follows:
1771-OBD 1756-OB16E w/ 1492-CONCAB005X
a) Current/Point 2A 1A
b) Current/Module 8A 4A
c) Surge Current/point 4A for 10ms 2A for 10ms
The 1771-OBD has a single 10A, 250V rectifier fuse (1/4 x 1 1/4 inch). The 1756-OB16E is electronically fused per
group. Refer to the 1756-OB16E Installation Manual for details on electronic fusing.
The 1771-OBD is rated 10V to 60V DC. The 1756-OB16E is rated 10V to 31.2V DC. If the load source voltage is greater than 30V
DC, then use the 1756-OC8 with the 1492-CM1771-LD008F conversion module.
Refer to your 1771-OBD and 1756-OB16E Installation Manual wiring schematics and diagrams for more details. Ensure 1756 output
module ratings are not exceeded. [Reference Doc: 41170-936 (Version 01)]
