Allen-Bradley 1746-A7 SLC 500 7 Slot Modular Chassis

Description

The Allen-Bradley 1746-A7 SLC 500 7 Slot Modular Chassis is a modular enclosure designed to build and configure SLC 500 control systems, supporting installation of SLC 500 series processors, I/O modules, communication adapters, and other compatible modules. It features 7 slots for flexible system customization, and can operate as a standalone unit or be combined with other local chassis to expand system capacity.

Key technical specifications include: IP30 protection rating, operating temperature range of 0 degrees Celsius to 60 degrees Celsius, storage humidity of 5% to 95% non-condensing, dimensions of 28.2 x 17.1 x 14.5 centimeters (11.3 x 6.8 x 5.8 inches), and weight of 1.1 kg (2.4 lbs). Constructed from aluminum alloy, it supports DIN rail mounting and is equipped with run and fault indicator lights, plus a rear connector for module integration.

The chassis includes embedded electronic circuitry connected to the power slot, which distributes power to inserted modules and facilitates data exchange between processors and modules. For multi-chassis configurations, it supports vertical connection via 1746-C9 or 1746-C16 cables, or horizontal connection via 1746-C7 cables, enabling expansion to a maximum of 30 I/O slots for extended signal line and system scalability.
