Allen-Bradley 1756-L73SXT GuardLogix-XT 5570 controller

The Allen-Bradley 1756-L73SXT is a GuardLogix-XT 5570 controller, a part of the Logix5000 family of controllers. It is a GuardLogix controller with safety control ability and conformal coating for high-performance and to operate in harsh and corrosive environments. It can withstand a temperature of -25 - 70 °C (-13 - 158 °F). It has 1756-L7SPXT safety partner along with it. It has greater processing capabilities and speed for process, motion, and high-performance logic. It has a USB port for communication. It can support up to 500 controller connections. The 1756-L73SXT controller has 8MB of user memory, 4MB Safety Memory, and 0.98MB of I/O memory. It can support 128,000 digital I/O and 4000 analog I/O. It draws a current of 5mA at 1.2V DC and 800mA at 5.1V DC. It has a power dissipation of 2.5W and a thermal dissipation of 8.5 BTU/hr. It weighs 0.55lbs and has an isolation voltage of 30V (continuous) for basic insulation. It can be installed in any slot of a ControlLogix 1756 Chassis and multiple controllers can also be installed in the same chassis. For safe communication, it uses ControlNet, DeviceNet or EtherNet/IP networks. The 1756-L73SXT controller can control or monitor I/O over the backplane or through I/O links. For controller diagnostics, it has a front display that provides runtime information. A 1 GB (1784-SD1) Secure Digital card comes pre-installed as an optional non-volatile storage which can be expanded up to 2 GB (1784-SD2).
