V. Wiring Diagrams (Cont’d)
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.
WARNING
1771-WH, WHF, WHFB Swing Arm
From 1171-OBDS
This Bul. 1492 cable consists of a cable wired to one 1756-OB16E RTB. Recommended cable lengths of 0.5M or 1.0M
(005=0.5M, 010=1.0M). See table 2 for other lengths.
The 1771-OBDS module output current limits versus 1756-OB16E limits are as follows:
1771-OBDS
1756-OB16E w/ 1492-CONCAB005X
a)

b)

c) Surge Current/Point
4A for 10ms
2A for 10ms
The 1771-OBDS has a single 12A, 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-OBDS is rated 10V to 40V 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-OBDS and 1756-OB16E Installation Manual wiring schematics and diagrams for more details. Ensure
1756 output module ratings are not exceeded.
