The Mitsubishi FX1s PLC is mounted on a pre-wired frame that facilitates easy connection. The mounting frame gives access to the PLC’s I/O capabilities providing an effective means for the student to test and debug the program prior to connecting to the application. All inputs and outputs are via colour coded safety sockets (4 mm) and ‘D’ type connectors. Simulation of inputs by the built-in switches. The controllers of the FX1S series deliver outstanding functionality. The integrated real-time clock and maintenance-free EEPROM with capacity for up to 2,000 program steps make the FX1S an autonomous and very service-friendly system.
