Mitsubishi Electric has enhanced the capability of its MELSEC iQ-F series PLCs with two new modules forming the basis of a compact, integrated safety system.
The modules connect to an FX5U or FX5UC PLC CPU, reducing wiring requirements.
Machine builders and systems integrators can easily and quickly implement a safety control system as no programming is necessary.
Mitsubishi says a key focus in the development of the new modules was to provide simplicity of set-up for the safety application.
A rotary switch on the front of the module enables the user to select from nine types of built-in programs, eliminating the need to load or develop the required sequence programs for safety control. This also reduces set-up time compared with a conventional architecture.
The principle of simplicity also extends to visualization. The PLC’s built-in web server make it easy to monitor the status of both the standard control and safety control system.
The FS5-SF-MU4T5 safety module and FX5-SF-8D14 safety input expansion module connect directly to the PLC, eliminating the additional wiring that would be required for a traditional safety controller or when constructing a system with safety relays.
Connection of the safety I/O has been simplified through the use of spring clamp terminals on the new modules.
The addition of the new safety modules to an FX5 PLC enables users to build a compact safety system that is certified to Category 4, PLe and SIL3 international safety standards.
