PLC (Base Units)
The PLC (base unit) is a basic base unit for mounting various units for PLC and an extension base unit. For PLC (base unit), select a unit corresponding to the PLC manufacturer's series. Care must be taken when selecting a product because the number of units that can be mounted is limited depending on the type of product. The basic base unit is a base unit for mounting units such as a power supply, CPU, memory, I / O, etc. There are normal types, high-speed types between multiple CPUs, dual power supplies, etc. The extension base unit is a unit that expands the I / O and memory to be controlled, and reinforces the functions by duplicating the power supply and CPU. There are two types of extension base units that require additional mounting of power supply units and types that do not require additional mounting.
