HONEYWELL CC-TDIL01 analog input/output terminal boards are usually divided into micro PLC, small PLC, medium PLC, large PLC, PC card PLC and PC-compatible PLC according to the scale of the I/O points carried by the CPU. Various scale classification standards are shown in the attached table.

A typical PLC typically consists of a CPU module, a power module, and some input/output modules that are plugged into a backplane. If the configuration is increased, it may include an operator interface, monitoring computer, communication modules, software, and some optional special function modules. Programmable controllers are not only easy to install, take up little space, consume little energy, have diagnostic indicators to help diagnose faults, and can be reused for other projects. Although there are PLC functions, such as running speed, interface types, data processing capabilities have been greatly improved, but the PLC has maintained its original design principle, that is, the principle of simplicity first.

·HONEYWELL CC-TDIL01 analog input/output terminal board adopts new advanced microprocessor and electronic technology to achieve fast scan times; Small, low-cost PLCS that can replace four to ten relays;

· High-density I/O systems provide space-saving interfaces at low cost;

· Intelligent I/O interfaces based on microprocessors extend distributed control capabilities, typical interfaces such as PID, network, CAN bus, fieldbus, ASCII communication, positioning, host communication modules and language modules (such as BASIC, PASCALC);

HONEYWELL CC-TDIL01 analog input/output terminal board · Including input/output module and terminal structural design improvement, so that the terminal is more integrated;

Special interfaces allow some devices to be connected directly to the controller, such as thermocouples, thermal resistance, stress measurement, fast response pulse, etc.

· The external equipment has improved the operator interface technology, and the system documentation function has become a standard function of the PLC.

These hardware improvements have led to the enrichment and development of the PLC product series, making the PLC from the smallest micro-PLC with only 10 I/O points to the large PLC that can reach 8000 points. These product families, with common I/O systems and programming peripherals, can form local area networks and connect to office networks. The whole PLC product family concept is a very cost-saving control system concept for users.
