HARDWARE SPECIFICATIONS

Front view of a typical MACQU Controller Box containing:

One typical Main Mimic Switching and Indicator Panel

&

Two typical Extension Mimic Switching and Indicator Panels

All MACQU Systems (Hydroponics, Climate, Fish, etc.) are equipped with one Controller Box (See Picture 1). The Controller Box is mainly the same for all Macqu Systems. It differs only in the “Main Mimic Switching and Indicator Panel” and the connections in the Main Clemens of Macqu Controller Box.

The Controller Box consists of:

  1. One MACQU-M card which is the main controller of the system. This card has the Analog to Digital (A/D) converter, 8 Digital Inputs (DI), 8 Digital Outputs (DO) and the Communication RS-232 module.

  2.  At least one MACQU-Ext card which is a Digital I/O card. There are two types of MACQU-Ext cards, one with 8 Digital Inputs and 8 Digital Outputs (MACQU-Ext-I/O) and one with 16 Digital Outputs (MACQU-Ext-O). There is no limit for the number of MACQU-Ext cards that one Macqu system can support.

  3.  A power supply card MACQU-PS, which produces the necessary voltages needed by MACQU-Ext and MACQU-M. MACQU-PS is either supplied by 220 Volt current (110 for USA and JP) or by the 6 Volt Backup Battery in the absence of network power.

  4.  A 4x20 Character Display MACQU-Dis. The information displayed can be changed from Macqu Program and the value of all the variables used in the system can be shown.

  5. One Main Mimic Switching and Indicator Panel with the appropriate mimic diagram depending on the specific application. The panel is equipped with a number of three position switches (on, off, auto) and indicating leds, which allow the user to control the system either manually or automatically. Depending on the application it may have additional alarm or working mode leds.

At least one Extension Mimic Switching and Indicator Panel for the additional Digital Output used in the application. The panel is equipped with a number of three position switches (on, off, auto) and indicating leds, which allow the user to control the system either manually or automatically

 

MACQU-M: Main Controller Card:

  1. Analog Inputs (16-SE ή 8DE), 10 samples/sec & 24 bit resolution & 1́V accuracy, 1 Ksample/sec & 16 bits. 

  2. Reference Frequency Output for AC measurements (2.5V, 0-100Hz)

  3. Fast Digital Outputs from electronic FET RELAYS

  4. Digital Inputs trough Optocoupler.

  5. DB-9 for RS-232 communication with the PC or other Controller, and power supply  (GND,+5,+12,-12 Volts).

  6. DB-9 for communication with Extension cards (through Ι2C protocol) or other Controller (with RS232) and power supply (GND,+5,+12,-12 Volts).

  7. Communication module RS-232 with Optocoupler. (up to 9600bps).

  8. Microcontroller 517Α and Memory 512Κ (or 8051 and memory 128Κ).

 

MACQU-Ext: Extension Card  I/o

  1. 8-Digital Outputs (8x1 SPDT RELAYS, 0.5 Amp & 120 VAC ).

  2. DB-9, for communication with the Controller through I2C protocol and   power supply  (GD,+5 Volts).

  3. 8-Digital Inputs with Optocouplers for MACQU-Ext-I/O (Read 8 Status or Frequencies 1 CPM-10KCPM). Alternatively, instead 8 DIs,   8-Digital Outputs are implemented in  MACQU-Ext-O.

 

MACQU-Dis: 4 x 20 LCD Display Panel

  1. 4 lines by 20 alphanumeric characters backlit display.

  2. Each line is configured to variable length segments to display a label or the value of a variable.

  3. The user is free to define the display segments through a special PC dialog.

  4. Virtually the user can define more than 4 lines (up to 16) which are shown sequentially on the display at 1 line/sec refresh rate.
