PLC Accessories

PLC accessories are auxiliary products such as connection bases, connectors, memory cards, expansion cables and software licenses that complete the installation, expansion and programming of a PLC system in the panel. They are used to connect the field cables of modules, join racks to each other, back up the program to a card, and activate software licenses. The category includes connection bases, connectors, memory cards, software licenses and a USB license key for ABB AC500 and AC500-eCo, Schneider Electric backbone expansion cables, a CPU memory card and Edge I/O NTS terminal blocks, and GMT mini PLC program upload adapters. Select the accessory according to the brand and series of the PLC, the type of CPU or module it will be installed on, the terminal construction (screw or spring), the cable length and the software function covered by the license. A connection base is not an I/O module or a CPU; it is the carrier on which the electronic unit sits and to which the cables are connected, and the CPU and module are purchased separately.
