ControlLogix 1756 I/O, communication modules, power supplies and chassis
56 Allen-Bradley ControlLogix 1756 I/O, power supplies, chassis catalog numbers, each with the ratings and the lifecycle status shown on its Rockwell product page (read on 3 November 2026). TDL quotes these parts as spares or as part of a project, and handles configuration, programming and commissioning on site.
- ControlLogix 1756 I/O modules, communication modules and power supplies install in 1756 chassis offered in 4, 7, 10, 13 and 17 slot sizes.
- ControlLogix power supplies are offered for 85-265 V AC input (1756-PA50, PA72, PA75) and 19-32 V DC input (1756-PB72, PB75); redundant assemblies 1756-PAR2/PBR2 use the 1756-PSCA2 chassis adapter.
How to read the catalog number
- Suffix letters on 1756 I/O: I = isolated (e.g. 1756-IB16I), D = diagnostic (1756-IB16D, 1756-OB16D), E = electronically fused (1756-OB16E), H = HART (1756-IF8H), IH = isolated HART (1756-IF8IH), as shown in the product descriptions.
