I. Module Description
The 1492-CM1771-LD006 conversion module provides field wire signal conversion from an A-B 1771-OAD, 10 to
138Vac, 16 point output module to a 1756-OA16, 74 to 265Vac(1), 16 point output module or from a 1771-OBD, 10
to 60Vdc(1) to a 1756-OB16E, 10 to 31.2Vdc output module. The conversion module provides the mating connec-
tor to the 1771-OAD and 1771-OBD module swing-arm/terminal block with the attached field wires. It routes those
signals via its 25-pin connector and a 1492-CONCABX pre-wired cable to compatible terminals on the
1756-OA16 or 1756-OB16E (refer to Wiring Diagrams on page 2 and 3 for details).
NOTICE: The 1771-OBD module had a single on-board mechanical fuse for all outputs. The 1756-OB16E is
electronically fused per group. Refer to the 1756-OB16E Installation Manual for details on electronic fusing.
