1771-P7/D - Power Supply - ALLEN BRADLEY

The 1771 power supplies provide 5V dc power directly to the chassis backplane. These power supplies occupy one or two slots in a 1771 chassis and can provide up to 8 A per supply to the I/O chassis.
These power supplies require no space outside the chassis, except for the 1771-P7P power supply. The 1771 power supplies connect directly to the chassis backplane and can be paralleled to provide greater current.
Redundancy is available for greater availability.

The 1771 series I/O modules offer digital, analog, and special-requirement modules. The 1771 I/O modules feature a wide range of: 

• signal interfaces to ac and dc sensors and actuators. 

• I/O densities with as many as 32 I/O points per module. 

• signal levels, including standard analog inputs and outputs and direct thermocouple and RTD temperature inputs. 

  PLC-5 controllers support 1771 I/O over these networks: 

  • Local I/O
  • Remote I/O
  • Extended-local I/O • ControlNet 

  When you select 1771 I/O modules, you must also select: 

  • Chassis
  • Power supply
  • Adapter module (if in remote chassis or extended-local chassis)
