About 1756-L61
Allen Bradley 1756-L61 is a ControlLogix controller. It has 2 MB of user memory and 478 kb of I/O memory available, optional with 128 MB of non volatile storage memory, and uses a 1784-CF128 CompactFlash storage card. It is a rack based controller that can be placed in any available slot in the 1756 ControlLogix rack. The compatible chassis of this controller are 1756-A4, 1756-A7, 1756-A10, 1756-A13, and 1756-A17. It has an open shell and can support up to 250 controller connections. It also has a built-in RS-232 serial communication port. The protocols supported by the RS232 port are DF1 full/half duplex, ASCII, DF1 radio modem, Modbus via logic, and DH-485.
It has a maximum digital I/O of 128000, a maximum analog I/O of 4000, and a maximum total I/O of 128000. The controller task for 1756-L61 includes 32 tasks, each with 100 programs, and event tasks: all event triggers. The 1756-L61 has multiple communication options, such as ControlNet, Data Highway Plus, EtherNet/IP, DeviceNet, SynchLink, remote I/O, and third-party process and device networks. The current consumption of the 1756-L61 controller is 1200 mA at 5.1V DC and 14 mA at 24V DC. The power consumption is 3.5 W, and the heat dissipation is 11.9 BTU/hour. It also has a continuous isolation voltage of 30V and has been tested at 720V DC for 60 seconds. Its working temperature is 0 to 60 degrees Celsius, storage temperature is -40 to 85 degrees Celsius, and the maximum ambient air temperature is 60 degrees Celsius.
Allen Bradley 1756-L61 is a ControlLogix controller with integrated 2MB user memory, allowing the controller to handle up to 128000 discrete I/Os and 4000 analog I/Os. This controller has an integrated RS232 communication port that can be logically configured as 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 for 250 connections. The network connection may vary depending on the communication module used. It also supports redundancy to improve system availability, which is usually necessary in critical systems.
