What are the common types of controllers? The main types of controllers include combinational logic controllers, CPU controllers, LED controllers, microprogram controllers, access control controllers, etc.
The combinational logic controller is mainly composed of four components: instruction register, opcode decoder, timing circuit, and instruction counter.
The CPU controller is mainly composed of three components: instruction register IR, program counter PC, and operation controller OC.
LED controllers are mainly classified into low-voltage LED product controllers, high-voltage LED product controllers, and low-voltage serial controllers.
The basic components of a microprogram controller are control memory and microinstructions.
The main categories of access control controllers include RS485 networked door controllers, TCP/IP networked door controllers, non networked door controllers, single door controllers, double door controllers, four door controllers and multi door controllers, one-way controllers, and two-way controllers.
