1756-IF16A controllogix input module

The hardware of the 1756-IF16A controller itself adopts a modular structure, and the product structures of various manufacturers are similar. Taking the Japanese Omron C200HE as an example, it adopts a bus template frame structure. The basic framework (CPU motherboard) is equipped with CPU templates, and other slots are equipped with I/O templates; If there are many I/O templates, the CPU motherboard can be connected to the I/O expansion motherboard through an I/O expansion cable, and I/O templates can be installed on it; Another method is to equip remote I/O slave stations, etc. All of these indicate that PLC manufacturers develop hardware components for users to choose from and configure them into PLCs of different scales. The openness of this hardware configuration brings a lot of convenience to manufacturers, distributors (agents), system integrators, and end-users, and greatly facilitates the sales and supply chain. This is a great success experience.

The I/O templates within 1756-IF16A, in addition to general DI/DO, AD/DA templates, have also developed a series of special functional I/O templates, which have opened up a way for PLC to be used in various industries, such as ASCII/BASIC templates for barcode recognition, PID templates for feedback control, high-speed counting templates for operation control and mechanical processing, single axis position control templates, dual axis position control templates, cam locator templates, etc There will be significant development in the future, such as RFID interface templates. In addition, related components for input and output, as well as input and output electrical isolation and ground isolation in strong interference situations, will also be improved. The CPU and memory in 216DB61 HESG324063R100J work together to complete control functions. It is different from DCS systems that handle parameters such as temperature, pressure, and flow. It adopts a fast scanning cycle, usually 0.1-0.2 seconds, and faster ones use a elimination cycle of 50 milliseconds or less. It is a digital sampling control system.
