DL205 PLC is the company’s an configurable and versatile solution in their portfolio, allowing up to five different CPU types, up to 16,384 I/O points, multiple communication options, Human Machine Interface (HMI), and a PID Controller with up to 16 built-in loops. Unlike other standard mainstream memories, company’s MRAM enables data integrity and reliability in harsh environments, and instant event save in the event of a power loss and without the need for a battery.

Before we developed the DL205, our prominent Japan automotive customer requested us to offer a next-generation PLC that does not require a battery backup,” recalls Nishida-san, corporate SVP, Koyo. “In addition to fulfilling our needs for a battery-less PLC system, Everspin MRAM enables our DL205 Series PLCs with highly reliable and robust memory to the benefit of our automotive and industrial customers. In addition, the system expands to Human Machine Interface (HMI) products to meet the growing customers’ expectations for system reliability, cost of ownership reduction, and eco-friendly management.

Koyo is a strong leader in modular PLC Automation for industrial and automotive companies in Japan and worldwide,” said Phill LoPresti, president and CEO, Everspin. “We are pleased Koyo has selected Everspin’s durable field-switched MRAM to provide unique, value-added benefits to Koyo’s customers.

The DL205 Series PLCs and expansion modules from Koyo Electronics utilize 1Mb parallel interface (MR0A16A) MRAM from Everspin.

Everspin’s field-switched MRAM is a fast non-volatile memory, offers high data retention and unlimited endurance, and is offered in a variety of packages, interfaces (SPI, QSPI, x8 and x16 parallel), and densities (up to 16-Mb). For MRAM benefits in higher density memory and storage applications, Everspin offers DDR-interface Spin Torque MRAM (ST-MRAM).
