Conversion Module Installation and Application Considerations
This Bul. 1492 cable consists of 2 separate cables (cable “A” and cable “B”) wired to one 1756-OB16D RTB. Each cable can be either
0.5M or 1.0M (005=0.5M, 010=1.0M). Ensure that cable A and cable B are connected to the correct module in the conversion.
The 1771-OB module output current limits versus 1756-OB16D limits are as follows:
1771-OB 1756-OB16D w/ 1492-C005005XF
a) Current/Point 1.5A 2A
b) Current/Module 6A 4A @ 60°C
c) Surge Current/Point 4A for 8.3ms 4A for 10ms
The 1771-OB has eight (8) 2A, 250V fuses - 1 per output. The 1756-OB16D is a DIAGNOSTIC MODULE. Refer to the 1756-OB16D
Installation Manual for details on diagnostics.
Refer to your 1771-OB and 1756-OB16D Installation Manual wiring schematics and diagrams for more details. Ensure 1756 output
module ratings are not exceeded. [Reference Doc: 41170-988 (Version 00)]
