Choosing I/O Type

CLICK CPU Modules with Built-in I/O

There are thirty-one CLICK CPU modules available in five classes, each with different combinations of built-in I/O types. The CLICK CPU modules all offer the same instruction set, and support all the available optional I/O modules. With the built-in I/O a CPU can be used as a ready-to-go PLC control system without any additonal I/O modules.

Basic CPU Modules

Basic CPU modules are the most cost effective CLICK CPUs and include include two RS-232 serial ports, eight discrete input and six discrete output points. Basic CPUs do NOT have a calender/clock or battery backup (there is a super-capacitor that will save retentive memory values for several days only). The only differences between the CPUs in the Basic family are the I/O type of the inputs and outputs.

Basic Ethernet CPU Modules

Basic Ethernet CPU modules include one Ethernet port, one RS-232 serial port, eight discrete input and six discrete output points. Basic Ethernet CPUs DO have the battery back-up, & calendar/clock. They also have a faster proceesor, and support "run time edits", PID, and high-speed inputs. The only differences between the CPUs in the Basic Ethernet family are the I/O type of the inputs and outputs.
