FAQ
FAQ
Q1: What is the primary function of the 1756-L72K controller?
The 1756-L72K is a high-performance programmable automation controller used in ControlLogix industrial automation systems.
Q2: What does the “K” suffix indicate?
The “K” designation means the controller includes conformal coating protection for harsh industrial environments.
Q3: How much user memory does the controller provide?
The controller includes 4 MB of user memory and 0.98 MB of I/O memory.
Q4: Does the 1756-L72K have built-in Ethernet communication?
No. Ethernet communication requires separate ControlLogix communication modules such as 1756-EN2T or 1756-EN3TR.
Q5: Which nonvolatile memory type is supported?
The controller supports Secure Digital (SD) cards for firmware and application storage.
Q6: Which energy storage module is compatible with the controller?
Compatible capacitor modules include 1756-ESMCAP and 1756-ESMCAPK.
Q7: Is the 1756-L72K still available?
Yes. Rockwell Automation currently lists the controller as “Active Mature.”
Q8: What is the main difference between the 1756-L72 and 1756-L72K?
The L72K version adds conformal coating protection while maintaining the same core controller functionality as the standard L72 model.
