The 1756-A17 chassis is a ControlLogix series chassis from Allen-Bradley/Rockwell Automation. It has 5 mounting tabs on the top and 5 additional mounting tabs on the bottom. The 1756-A17 ControlLogix chassis can be used with or without SEM screws, but the presence or absence of SEM screws will determine how much and what kinds of other hardware that the chassis needs. With SEM screws, the 1756-A17 chassis needs 5 Phillips screws, 5 flat washers, 5 split-lock washers, and 5 SEM screws, and without SEM screws, the chassis needs 10 Phillips screws, 5 flat washers, 5 split-lock washers, and 5 star washers. The 1756-A17 ControlLogix chassis can operate safely at 32 to 140 degrees Fahrenheit and it has no enclosure.

The 1756-A17 Allen-Bradley 17 SLOT CHASSIS RACK may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

Top clearance and 5.1 cm (2.0 in.) bottom clearance.

The 1756-A17 Standard Chassis includes inherent time-stamping capabilities for SOE applications. The chassis backplane distributes power to each of the modules within the chassis by providing a high-speed communication path between modules. It requires a Bulletin 1492 wiring IFM or an RTB to connect all the field-side wiring. The 1756-A17 Standard Chassis provides easy maintenance with the RIUP feature. For preventing replacement errors, it also offers electronic keying. In case of any system or field side failure, its comprehensive diagnostic feature helps identify the fault. It is compact, cost-effective, and easily compatible with items such as PanelView operator.
