Maxim II Controller

Digital / Controllers

This product has been superseded.

Replacement Product: SKIA 8C

The Innotech Maxim II Controller is a state of the art digital processing system that has the capability of controlling various types of commercial 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 Innotech devices that support Global Net Comms.

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.

Innotech Maxim II Controllers are designed for mounting inside a control cubicle. The Maxim II offers a variety 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 provides all the features of a stand-alone Maxim I but with many additional features.

The creation of control strategies is made simple by the use of the Maxim Config configuration utility - MAXCon. This utility, with its powerful Graphical User Interface, allows the user to create an entire control strategy in block-diagram form.

Typical applications include:

Air conditioning and heating systems
Lighting control
Time clock controller
Monitoring device
Distributed I/O points controller
Cold/Freezer Rooms

MaxCon - Maxim Controller Configuration utility. It allows the user to internally configure a Maxim by a simple point-and-click approach on a PC running Windows.
MaxMon - Monitoring and debugging utility designed to help with commissioning and trouble-shooting a Maxim Controller.
MaxSim - Utility that simulates a Maxim II Controller. The virtual Maxim II can be powered on, configured and interrogated in the same way as a physical Maxim II.
iComm- Communications server used by Innotech software to communicate with Innotech digital controllers.
MaxTract - Log extraction utility for a range of Innotech digital controllers. It allows extraction of all or part of the history log data residing on a Maxim controller into a specified data format.
Innograph - Designed to specifically cater for the data log graphing capabilities of Innotech controllers, and it has the flexibility to display data log graphing information from other sources.
Supervisor - A dynamic monitoring utility for Innotech controllers. It provides all the functionality that is available from an Innotech controller display panel with greater ease-of-use and flexibility.
Magellan - Event-driven, object oriented real-time Supervisory Control and Data Acquisition package. It provides a simple, mechanism to design trivial or sophisticated supervisory or control programs.

Power Supply

24VAC ± 10% @ 50/60 Hz
24VDC ± 10%

Transformer nominal rating of 5VA.

The operating voltage must meet the requirements of Safety Extra Low Voltage (SELV) to EN60730. The transformer used must be a Class 2 safety transfomer that has the energy and voltage limiting characteristics as described in the National Electrical Code, ANSI/NFPA70. It must also be sized and fused in compliance with local safety regulations.

Temperature Ratings

Storage: 0 to 50°C non-condensing
Operating: 0 to 40°C non-condensing

Inputs
6 Universal Inputs, configurable via software to either:

Dry Digital Inputs
Voltage Digital Inputs
10K Thermistor Inputs
0-10V DC
LUX sensor input (Light sensor ORP12 LDR)
Dry Duty Cycle Inputs
Voltage Duty Cycle Inputs
Dry Pulse Counter Inputs
Voltage Pulse Counter Inputs

Notes:

Exact Input combinations may be limited by the device
Input accuracy is ±0.1 volts
Error is less than 0.2% with 15Hz square wave input
LUX Sensor Input mode is useful for switching based on ambient light levels, but is not suitable for any operation which requires the accurate measurement or recording of light levels

Outputs

6 Digital Outputs:

6 x normally open relays (2 amp @ 24VAC)
Recomended use of pilot relays when switching
high voltage/inductive loads

4 Analogue Outputs:
- Analogue Outputs 1 and 2 can be configured individually as either linear 0-10VDC or PWM outputs
- Analogue Outputs 3 and 4 are dedicated linear 0-10VDC outputs
- Output Load > 2kOhms

Note: Up to 3 solid state relays can be connected in series, to the analogue outputs when configured as PWM.

Battery
Contains a Lithium Type Battery, Dispose of Properly.

Type CR-2032 Lithium
Nominal voltage 3 Volts
Shelf life ~5 Years, dependant on ambient temperature

Caution: Risk of explosion if battery is replaced with an incorrect type.

Enclosure/Mounting
The Maxim II is housed in a rectangular case suitable for DIN Rail mounting. The housing is moulded from flame retardant plastics recognised by UL as UL 94-V0.

Data Logging
The Maxim II Controller comes with a powerful Data Logging facility. Data Logging can be assigned to hardware and software points. Approximately 50,000 time stamped readings can be stored on the Maxim II. All data is stored in a 512 kilobyte non-volatile flash RAM. When the memory becomes full, new readings replace the oldest readings. All logged data points can be extracted by using the MAXTract Software tool.

Communications

RS485:

5 way plug in connector for local/remote computer access for purposes of uploading, downloading and monitoring configuration programs and the extraction of logged data, via a 485/232 converter.
