A failsafe PLC head module for a modular automation system, combining safety and standard control in a single controller with SD-card program storage.
This is a head module for a modular I/O system, running failsafe and standard control logic side by side. It connects to a dedicated safety network for safety-related networking and can additionally act as a PROFINET, Modbus/TCP, or EtherNet/IP node — letting one controller cover both the safety loop and general machine I/O.

Runs failsafe and standard logic together as the head module of a modular I/O station.
Bridges a safety-rated network with standard PROFINET, Modbus/TCP, or EtherNet/IP equipment on the same line.
Yes, it is designed to be the safety controller of a machine, working with other devices such as light curtains, laser scanners, safety switches and emergency stops through the I/O system. The exact I/O modules and wiring depend on your machine, so please share your requirements with the team.
No. PL e describes the controller. The Performance Level of a safety function depends on the whole chain, from the input device through the logic to the output, and how it is built. Prazamana's SISTEMA analysis models the chain and documents the achieved PL against what your risk assessment requires.
Prazamana has delivered safety upgrades that combine fencing, light curtains, interlocks, Safety PLC systems and emergency stops on robotic cells and press machines. contact the team through the Contact page to discuss the support you need with selection, integration and documentation.
