Conversion Module Installation and Application Considerations
This Bul. 1492 cable consists of 2 separate cables (cable “A” and cable “B”) wired to one 1756-OB16I 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-OQ module output resistive current limits versus 1756-OB16I limits are as follows:
1771-OQ 1756-OB16I w/ 1492-C005005XT
a) Current/Point 2.25A 2A
b) Current/Module 9A 8A
c) Surge Current/Point 4A for 10ms 4A for 10ms
The 1771-OQ is rated 10V to 32V DC. The 1756-OB16I is rated 10V to 30V DC.
Refer to your 1771-OQ and 1756-OB16I Installation Manual wiring schematics and diagrams for more details. Ensure 1756 output
module ratings are not exceeded. [Reference Doc: 41171-033 (Version 00)]
