The 1756-L55M13 is a powerful processor module within the ControlLogix platform. This Logix5555 controller delivers 1.5 MB of RAM for user logic and data storage. Additionally, it offers 208 KB of dedicated I/O memory. This combination supports substantial control applications. The module handles up to 128,000 maximum I/O points. For analog signals, it manages 4,000 inputs and 2,000 outputs. This processor operates with a fast program scan time of just 0.08 milliseconds. Consequently, it suits time-critical automation tasks effectively.
This processor draws a backplane current of 1.23 A at 5.1V DC. Meanwhile, it consumes only 14 mA at 24V DC. The module dissipates 5.6 W of power. Its thermal dissipation is rated at 19.1 BTU/hr. The isolation voltage is 30V continuous with basic insulation. Furthermore, it withstands 707V DC for 60 seconds during testing. The conducted RF immunity is 10V rms with 1 kHz sine-wave 80% AM from 150 kHz to 80 MHz. The 1756-L55M13 uses a replaceable lithium battery. Specifically, it is compatible with the 1756-BA1 or 1756-BATM battery types. For programming, you need either the 1756-CP3 or 1747-CP3 cable.
This controller supports a wide range of communication options. For instance, it works with EtherNet/IP, ControlNet, and DeviceNet networks. Additionally, it supports Universal Remote I/O serial and Data Highway Plus. The 1756-L55M13 also handles Modbus communication via ladder routines. Furthermore, it is compatible with SynchLink and DH-485 protocols. Therefore, this module integrates smoothly into diverse industrial environments. You can use it in redundant controller systems as well. However, both controllers must reside on the same ControlNet network for redundancy.
The operating temperature ranges from 0 °C to 60 °C. In contrast, the storage temperature spans -40 °C to 85 °C. The relative humidity must stay between 5% and 95%, non-condensing. This module withstands vibration of 2G at 10 to 500 Hz. Moreover, it handles an operating shock of 30G. The non-operating shock rating is even higher at 50G. The 1756-L55M13 is an open-style module. As such, it does not carry a specific enclosure type rating.
First, insert the module into any available slot in the 1756 chassis. Next, secure it firmly by tightening the retaining screws. Then, connect the appropriate programming cable to the port. For battery replacement, only use the recommended 1756-BA1 type. Power down the chassis before inserting or removing the processor. Always follow standard ESD precautions during handling.
