FAQ
FAQ
Q1: What is the purpose of the 1756-L7SPK module?
The 1756-L7SPK is a GuardLogix safety partner controller used together with specific GuardLogix primary controllers to provide redundant safety processing for SIL 3 and PLe safety applications.
Q2: Which controllers are compatible with the 1756-L7SPK?
It is designed to operate with GuardLogix controllers such as the 1756-L71S, 1756-L72S, and 1756-L73S.
Q3: Can the 1756-L7SPK operate as a standalone PLC?
No. It functions only as a safety partner module and must be paired with a compatible GuardLogix safety controller.
Q4: What safety certifications does the module support?
The module supports SIL 3 (IEC 61508) and Performance Level e (ISO 13849) safety requirements.
Q5: What does the “K” suffix indicate?
The “K” suffix indicates conformal coating for additional environmental protection in harsh industrial conditions.
Q6: Does the module contain user application memory?
The module works in conjunction with the primary GuardLogix controller and mirrors safety-related processing rather than acting as an independent controller.
Q7: What chassis is required for installation?
The module installs into a standard 1756 ControlLogix chassis.
Q8: Is the 1756-L7SPK still available?
Yes. Rockwell Automation currently classifies the module as Active Mature within the GuardLogix platform.
