Programmable Logic Controllers (PLC) from Prime Controls Co. Maple Systems
Maple Systems has been a quality-driven leader in the industrial controls marketplace since 1983, offering affordable control solutions for industrial, OEM, automation, and municipal applications.
Programmable logic controllers (PLC) are electrical devices used to control and automate industrial processes by reading digital and analog inputs such as push buttons, limit switches, temperature or pressure sensors, and then writing to digital or analog outputs to power devices such as LEDs, solenoids, relays, or motors. PLC programming is usually done using Ladder Logic (also known as Ladder Diagram), which is a graphical programming language, but other IEC 61131 plc coding languages such as Structured Text can also be used depending on the PLC.
