Output Module Specifications
Description:
Specification: 1746-
(4)
(4) Series A, B, and C 32-point output modules are fused to protect external wiring, one fuse per common. The fuses are
non-replaceable and are rated at 2.5A. 1746-OB32, OV32 Series D modules are not fused and have a higher current rating
than Series A, B, and C.
