STMicroelectronics’ IPS8160HQ and IPS8160HQ-1 new high-side switches provide eight channels in a compact QFN48L package — with the added value of built-in protection and diagnostics. This unique combination of features saves space and enhances reliability in PLC modules used for driving heavy loads and unidirectional motors in vending machines. Additional applications for the new switches include I/O peripherals…
Renesas releases new PLC modem IC for high-speed, long-distance communication
Renesas Electronics Corporation, a supplier of advanced semiconductor solutions, has introduced the R9A06G061 power-line communication (PLC) modem IC. The R9A06G061 delivers high-speed communication at up to 1Mbps over long distances of a kilometer or more — without the need for relays, expanding the range of practical applications for PLC. Optimized analog peripheral functions reduce the…
PLC : An Overview
Programmable logic controller is a digital computer used for the automation of various electro-mechanical processes in industries. These controllers are specially designed to survive in harsh situations and shielded from heat, cold, dust, and moisture etc. The hardware components of a PLC system are CPU, Memory, Input/Output, Power supply unit, and programming device. PLC consists of a microprocessor which is programmed using the computer language. A visual programming language known as the Ladder Logic was created to program the PLC. The program is written on a computer and is downloaded to the PLC via cable. These loaded programs are stored in non – volatile memory of the PLC.
