The Schneider Modicon M221 Series Logic Controller is a compact and powerful solution designed to meet the automation needs of a wide range of applications. With its 24 V dc power supply and a modest current draw of 0.5 A, this controller is an efficient choice for managing various processes. The unit's dimensions, 110 x 70 x 90 mm, make it suitable for installations where space is at a premium.
This PLC controller is equipped with a range of features that facilitate robust control and monitoring tasks. It boasts a fast output frequency of up to 100 kHz for PWM/PLS mode at specific outputs, ensuring precise control for demanding applications. The controller also includes a built-in real-time clock and supports up to 14 adjustable PID regulator loops, making it ideal for time-sensitive processes and complex control scenarios.
For connectivity, the controller offers a USB port with a mini B USB 2.0 connector, a non-isolated serial link with an RJ45 connector and RS232/RS485 interface, and an Ethernet port with an RJ45 connector. These options provide flexibility for programming, communication, and integration into existing networks.
The unit's memory capacity includes 256 kB for user applications and data RAM, with the ability to handle 10000 instructions, and an additional 256 kB for internal variables RAM. For data backup, there is 256 kB of built-in flash memory, and an optional 2 GB SD card can be used for extended data storage.
Local signalling is made easy with a series of LEDs that indicate power, run status, module error, SD card access, battery status, I/O state, and Ethernet network activity and link status. This immediate visual feedback is invaluable for troubleshooting and monitoring the system's performance.
Designed to operate within a temperature range of -10 to 55 °C for horizontal installation and -10 to 35 °C for vertical installation, the controller is robust enough to handle challenging industrial environments. It also has a high degree of resistance to vibration and shock, ensuring reliable operation even in demanding conditions.
Overall, the Schneider Modicon M221 Series Logic Controller is a versatile and reliable choice for automating a wide array of processes, offering both performance and ease of use in a compact package.
