The 1756-L61 processor module has 128,000 maximum I/O and 4,000 Input/2,000 Output for the maximum analog I/O. The backplane current at 5 Volts DC is 1.2 Amps and the backplane current at 24 Volts DC is 14 mA. Besides that, it is relevant to mention its program scan time is 0.08 milliseconds.

The ControlLogix controller comes in a small and cost-effective package and its modularity enhances the overall system that is being controlled by it. The users can easily modify and tailor the module according to requirements and in that way reduce costs significantly. The 1756-L61 controller can be part of a system that consists of an independent controller and I/O modules in 1 chassis or part of the more advanced system with multiple controllers in 1 chassis, multiple controllers that operate in combination through network communication or multiple platform I/O. The 1756-L61 controller comes with a built in RS-232 serial port for communications and the available communication modules include the DF1 full/half-duplex, DF1 radio modem, DH-485, Modbus via logic, and the ASCII. Besides this, the controllers support various optional communication solutions in EtherNet/IP, ControlNet, DeviceNet, Data Highway Plus, SynchLink, Remote I/O, and third-party processes and networks for devices. The controller supports the 1756-BA1 or 1756-BATM battery for its backup power. The operating temperature of the controller should be between 0 and 60 degrees Celsius (32 and 140 degrees Fahrenheit) and it can withstand a vibration of 10 to 500 Hertz. The controller operates in environments with a relative humidity of 5 to 95%. The controller weighs only 0.32 kilograms or 0.71 pounds.
