About ControlLogix series chassis Module 1756-A17

The AB 1756-A17 is a ControlLogix component. This is a 17-slot chassis that is used to mount ControlLogix modules including processors, I/O modules, specialty modules and encompass partner modules.

The 1756-A17 provides module housing including the necessary backplane connection to allow internal module connection and distribution of bus power through the embedded electronic circuitry and provided mounting slots to the chassis. It has a power consumption of 1.5 A @ 1.2VDC; 4A/4A @ 3.3 VDC; 15 A/6 A @ 15 A/6 A and 2.8 A/2.8 A @ 24VDC.

The 1756-A17 supports horizontal mounting only and requires a minimum cabinet size or available space of 76.2 x 91.4 x 20.3 cm (30 x 36 x 8 in.). The provided 10 mounting tabs permit direct panel mounting to the enclosure subpanel for convenient and fast installation. This chassis weighs 2.20 kg (4.8 lb).

When mounting 1756-A17 chassis with nearby ControlLogix chassis, specific space requirements are 10.2 cm (4.0 in.) plus the width of the power supply (left side), 7.7 cm (3.0 in.) plus the width of the power supply (right side), 15.3 cm (6.0 in.) Top clearance and 5.1 cm (2.0 in.) bottom clearance.

The 1756-A17 are available in 3 chassis revisions, specifically, series A, B and C. Series C specifically offers improved slot guidelines, ventilation, tougher mounting tabs, extra holes for mounting tabs and additional ground screw for termination to the panel grounding.

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.
