This Modicon MCM memory card is used to save safety PLC configuration data for subsequent transfer to a new PLC without using a PC. It enables quick and easy restart of your safety controller after an incident, without using a PC or checking configuration parameters. Its capacity is 512MB. Its dimensions are 18mm (Depth), 21.5mm (Height), and 2mm (Width). It weighs 0.004kg. The modular safety controllers Modicon MCM are certified by TüV SÜD meeting the industrial safety standards of Category 4, PL e according to EN/ISO 13849-1 and SILCL 3 according to IEC/EN 61508 and IEC/EN 60261. This memory card is compatible with the expansion modules and the safety controllers CPU. The memory card instals in the slot in the rear panel of the controller. The Modicon MCM modular safety controller system provide flexibility and scalability from 8 inputs, 2 dual/4 single channel outputs up to 128 inputs, 16 dual/32 single channel outputs, up to 32 or 48 diagnostic status outputs. Modicon MCM modular safety controller system are designed to monitor multiple safety functions on and around a machine to minimise the risk of people accessing the dangerous moving parts of the machine.
