The Allen-Bradley 1756-L61 is a ControlLogix controller. It has 2 MB of user memory and 478 KB of I/O memory, as well as an optional 128 MB of non-volatile storage memory, using a 1784-CF128 CompactFlash memory card. It is a chassis based controller that can be placed in any available slot in the 1756 ControlLogix chassis. Compatible enclosures for this controller are 1756-A4, 1756-A7, 1756-A10, 1756-A13, and 1756-A17. It uses an open chassis and can support up to 250 controller connections. It also has a built-in RS-232 serial communication port. Protocols supported by the RS232 port include DF1 full duplex/half duplex, ASCII, DF1 radio modem, 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 process and device networking. The current consumption of the 1756-L61 controller is 1 mA at 1200.5V DC and 24 mA at 14V DC. Power consumption is 3.5W and heat dissipation is 11.9BTU /hr. It also has a continuous isolation voltage of 30V and was tested at 720V DC for 60 seconds. It has an operating temperature of 0 to 60 degrees Celsius, a storage temperature of -40 to 85 degrees Celsius, and a maximum ambient temperature of 60 degrees Celsius. Relative humidity is between 5% and 95% (non-condensing), vibration is 500 g at 2 to 10 Hz, and operating and non-operating 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 for ASCII, DF1 full/half duplex, DF1 radio modem, DH-485 and Modbus.

The controller supports the implementation of independent and distributed I/O applications. Although the module allows 250 connections.
