Maxim II

Part Number: 73-8000-02

Maxim II

The MAXIM II Controller is a state of the art digital processing system that has the capability of controlling various types of industrial, commercial and domestic systems.  The MAXIM II can operate as a standalone device, using its own universal inputs and analogue and digital outputs to receive information and control external equipment, or as part of a network of  devices that support Global NetComms.

List of Benefits

  • 100 millisecond cycle/scan time
  • 6 configurable universal inputs
  • 6 digital relay outputs
  • 4 analogue outputs
  • User interface on a 4 line, 20 character LCD Display
  • 25 user defined watches

 

MAXIM II Controllers are designed for mounting inside a control cubicle and offers a varierty of inputs and outputs enabling it to monitor and control all types of external plant and equipment. Although the MAXIM II is flexible, it is primarily designed for the air conditioning and building automation industry. The small size of the MAXIM II also gives it the advantage of being  fitted in small places without taking up valuable switchboard real-estate.

The MAXIM II's configuration program is developed on a computer using a Windows based program. This allows the user to configure the internal processes of the MAXIM II by using a graphical programming tool. The user places various process blocks and interconnecting lines to design the required control algorithm for the system.

A connector on the bottom right side of the case provides an RS485 serial link to the computer via a 485/232 converter for downloading the configuration program. This link may also be used to upload logged data or the program back out of the controller for modification or debugging purposes.
