PRODUCT INFORMATION
Product Overview
The Allen-Bradley 1746-A10 is an SLC 500 modular mounting chassis. It provides 10 slots for processor, I/O, and specialty modules. The unit mounts directly to an enclosure panel using six dedicated mounting tabs. Installers secure the tabs with SEM screws or Phillips screws with star washers. This physical framework maintains backplane connectivity across all ten module positions.
The backplane delivers up to 10 Amps at 5.1V DC. It also supplies up to 2.88 Amps at 24V DC. For expanded architectures, the unit connects to one or two additional chassis. Interconnection requires a compatible chassis interconnect cable. Operating temperatures range from 0 to 60 degrees Celsius. Storage temperature limits are -40 to 85 degrees Celsius with non-condensing relative humidity between 5 and 95%.
