It also has a built-in RS-232 serial communication port. Protocols supported by the RS232 port include DF1 full/half duplex, ASCII, DF1 radio modems, Modbus via logic, and DH-485. It has a maximum digital I/O of 128,000, a maximum analog I/O of 4,000, and a maximum total I/O of 128,000. The controller tasks of the 1756-L61 consist of 32 tasks, 100 programs per task, and event tasks: all event triggers. The 1756-L61 has a variety of communication options, such as ControlNet, Data Highway Plus, EtherNet/IP, DeviceNet, SynchLink, Remote I/O, and third-party processes and device networks.

The current consumption of the 1756-L61 controller is 1 mA at 1200.5V DC and 24 mA at 14V DC. The power consumption is 3.5W and the heat dissipation is 11.9 BTU/ hour. It also has a continuous isolation voltage of 30V and has been tested for 60 seconds at 720V DC. It has an operating temperature of 0 to 60 degrees Celsius, a storage temperature of -40 to 85 degrees Celsius, and a maximum ambient air temperature of 60 degrees Celsius. The relative humidity is between 5% and 95% (non-condensing), the vibration is 500 g at 2 to 10 Hz, and the working and non-working shocks are 30 g and 50 g respectively. The Allen-Bradley 1756-L61 is a ControlLogix controller with an integrated 2MB of user memory that enables the controller to handle up to 128,000 discrete and 4,000 analog I/ OS. The controller has an integrated RS232 communication port and can be logically configured to ASCII, DF1 full/half duplex, DF1 radio modem, DH-485 and Modbus.

This controller supports the implementation of independent and distributed I/O applications. Although the module allows 250 connections. Depending on the communication module used, the network connection may vary. It also supports redundancy to improve system availability, which is often required in critical systems.
