1769-L31 AB Allen-Bradley PLC Modular Controller 1769 Series Original brand new

1769-L31 AB PLC Modular Controller 1769 Series Original brand new

1769 Modular Controllers 

The 1769-L3x CompactLogix system is a Logix solution for low-end to medium applications. Typically, these applications are machine-level control applications that require limited I/O quantities and limited communication capabilities.
The 1769-L3x CompactLogix system provides:

a built-in RS-232 serial port on every L3x controller.built-in communication ports for EtherNet/IP or ControlNet networks.a 1769-SDN communication interface module for I/O control and remote device configuration over DeviceNet.Compact I/O modules providing a Compact, DIN-rail or panelmounted I/O system.
