Digital Controller for 20-Channel Monitoring and Control
The MAXIM III Controller is a state-of-the-art digital processing system capable of controlling industrial, commercial and domestic systems. It can operate standalone, using its universal inputs and analogue and digital outputs to receive information and control external equipment, or as part of a network of devices supporting Global NetComms.
Designed for mounting inside a control cubicle, it offers a variety of inputs and outputs to monitor and control external plant and equipment. Although flexible, it is primarily designed for the air conditioning and building automation industry.
The configuration program is developed on a Windows-based graphical programming tool, where process blocks and interconnecting lines design the control algorithm. Programs and logged data are transferred via RS485 serial link or optional Ethernet, with up to 2 MBytes of data logging for up to 300,000 time-stamped readings.
