Product Overview
The 1756-L73S is an Allen-Bradley GuardLogix 5570 series programmable automation controller (PAC) offering both standard and safety control in a single module. It provides 8 MB of user memory and 4 MB of dedicated safety memory, with 0.98 MB of I/O memory and 1 GB of non-volatile storage via SD card. Installed in a 1756 chassis, the 1756-L73S executes standard logic and communicates with a safety partner for SIL 3 / PLe functional safety applications-commonly used in safety-integrated machine and process control systems.
Best Suited For
- Safety-integrated machinery requiring SIL 3 / PLe compliance
- ControlLogix applications needing combined standard and safety logic
- Systems with high I/O point counts (up to 128 000 digital, 4 000 analog)
- Installations requiring onboard non-volatile memory for program retention
- Use in environments with energy storage module (no lithium battery)
