Product Description:

Developed by Kollmorgen, the Digital MMC-D2 is a part of the MMC Standalone Smart Drive series. This gadget ensures that everything runs more smoothly and effectively whether you are constructing from scratch or upgrading current systems. Designed to run two MMC-SD-D drives concurrently, this sophisticated control module provides a simplified approach for challenging motion control uses. Its solid design maintains exact and effective performance in many different industrial settings.

Made to run best between 0°C and 55°C, the module is a dependable solution for many different kinds of industrial and commercial use. This top-rated module is mostly composed of a 32-bit RISC processor with a numerical coprocessor that provides fast processing capacity necessary for real-time control activities. With 384K of application memory, 256K of RAM and 64K of user memory support the system. Its two-megabytes flash disk for data storage and three-volt coin cell (BR2032 lithium battery) help to preserve system integrity during power outages.

The Digital MMC-D2 excels mostly in connectivity features. Supporting 100Base-Tx and 10Base-T half-duplex communication, it comprises an Ethernet port complying with IEEE 802.3/802.3u standards. Capable of baud rates up to 115.2K, this drive controller also has RS232 and RS485 connections, thus enabling flexible communication choices. Operating at a nominal 24 VDC, it offers eight general-purpose DC inputs and eight DC outputs with short circuit safety for both input and output activities. Within an input voltage range of 20 VDC to 30 VDC, the system runs effectively consuming 250 mA from the MMC-SD Drive.
