UNITROL 1020 and UNITROL 1010 are the latest products of the UNITROL 1000 family. For most reliable operation, the communication and control tasks are split in separate controllers. The non-volatile flash memory of the AVR stores events and data logs to enable fault analysis and fast trouble shooting. Time synchronization is done over Ethernet communication, and the events and data logs are time-stamped.

UNITROL 1000 is provided with modern communication ports like Ethernet and USB for connection of the PC-based commissioning tool CMT1000. Besides it is possible to power up the controller of the device via USB port. Thus the user can download files or configure the device even when no input power is available. AVR output stage is based on proven IGBT technology, which allows AC and / or DC voltage inputs from different sources.

UNITROL 1020 and UNITROL 1010 are designed for a wide range of ambient temperature and harsh environmental conditions and can be mounted directly on the machine.
