The 1772-LE control module is a PLC 5 processor control module manufactured by Allen-Bradley. The module helps to communicate between different processors.  It is a Series A device and it can be mounted into a system chassis. It can also be added to a single-slot input module. It uses 10 to 32 Volts DC digital voltage for regular work. It is designed with 40 terminals. There are 32 input/output ports in the module. The contact plating of the module is made of tin and the outer layer of the module is conformally coated. It requires a screw torque of 7-9 pounds on an inch. No external power is required to operate this module. The 1772-LE control module has a typical AC signal delay of 29 milliseconds and a DC signal delay of 30 milliseconds. The module uses block transfer as well as the Allen-Bradley 1772 series input/output structure. The module has a dimension of 115 x 317 x160 millimeters. The module meets the UL, CSA, CE, C-Tick, ODVA, and European Union directives.

The 1772-LE control module is manufactured with a variety of control features. It uses parity error detection to detect single-bit errors and multi-bit errors. The processor module can be used to add commands and data standards to the local processor. It can also read the resulting data values, status conditions, diagnostic data, and running information. For networking and communication, the module uses the Ethernet/IP, ControlNet, and DeviceNet networks. It helps to provide a cost-effective connection to a wide range of devices. The 1772-LE control module has no waterproof ability and it should be protected against liquid sprays and splashes.
