Available. The Mitsubishi Electric Q35B is a 5-slot main base unit designed for the MELSEC-Q series programmable logic controllers (PLCs). This compact base unit provides a centralized platform for assembling control systems, accommodating one power supply module, one CPU module, and up to three I/O or intelligent function modules. Its dimensions are 245 mm in width, 98 mm in height, and 44.1 mm in depth, with a weight of 0.25 kg. The Q35B is suitable for applications requiring a compact control system, such as conveyors, packaging machines, and assembly lines. It supports a wide range of modules, including I/O, analog, communication, and motion control modules, offering flexibility to meet various control needs. The base unit is extendable, allowing for system expansion when more module slots are required. Installation is facilitated by M4 screw holes or 4.5 mm diameter holes for M4 screws, and it can be mounted using screws or on a profiled rail with an integrated adapter. The Q35B is compatible with power supply modules Q61P-A1, Q61P-A2, and Q63P, and is part of the MELSEC-Q series, which is known for its flexibility and scalability in industrial automation applications.
