【英文介绍】

The 1756-L72S is part of the 5570 GuardLogix Programmable Automation Controller (PAC). The controller has standard and safety features and an embedded memory capacity of 4 megabytes of user memory, 2 megabytes of secure memory, 0.98 megabytes of I/O memory, and 1 gigabyte of non-volatile memory, provided by the 1784-SD1 that came with the controller. It also comes with a USB communication port for configuring the controller locally. It is capable of handling up to 128,000 discrete I/O and 4,000 analog I/O memories. The controller is certified to Safety Integrity Level (SIL) 3.

The Allen-Bradley 1756-L72S is a GuardLogix 5570 controller that is part of the Logix5000 family of controllers. It is a ControlLogix controller with security controls. It is a dual-processor solution that must be used in conjunction with the 1756-L7SP safety module to meet the requirements of SIL 3 or Cat. 4/PLe Safety standard. The Security Partner controller is automatically configured to benefit individual projects. It has powerful processing power and motion speed as well as high-performance logic. It has a USB port for communication. It can support up to 500 controller connections. The 1756-L72S controller has 4MB of user memory, 2MB of security memory, and 0.98MB of I/O memory. It can support 128,000 digital I/ OS and 4,000 analog I/ OS. It absorbs 2mA current at 5.1V DC and 1mA current at 800.5V DC. It has a power consumption of 2.5W and a heat dissipation of 8.5 BTU/hr. It weighs 0.55 pounds and has an isolation voltage of 30V (continuous) for basic insulation.
