1771-A4B Allen-Bradley Brand New 24A Backplane Chassis

1771-A4B Allen-Bradley Brand New 24A Backplane ChassisProduct Overview The Allen Bradley 1771 A4B operates as a high capacity, heavy duty 16 slot universal input output chassis designed for the classic Rockwell Automation PLC 5 control platform. This backbone enclosure provides the physical mounting structure, data communication pathways, and regulated power distribution lines necessary to operate complex industrial automation systems. Featuring a rugged backplane rated for up to 24 Amps of continuous

Newer versions like the DSLC-2 utilize Ethernet-based configuration via a web browser or Toolkit software

unblemished terminal screws

For AC-coil versions

This module serves as the primary physical and electrical interface for Galvanically Isolated (GI) and Intrinsically Safe (IS) analog input signals

Integrated electronic current limiting at 21 mA protects the module internal circuitry against accidental short circuits in field wiring

Can I access HART diagnostics through all 16 channels

It draws all its required 5 V DC working current straight from the backplane

Ruggedized protection: The module housing resists the electromagnetic noise typical of large motor control centers and power generation halls

You can upgrade the local layout to a larger hardware footprint by choosing an alternative model

This eliminates the need for expensive cabinet cooling fans or air conditioning units in extreme factory environments
