AN #189 - RECON SX controller Print
RECON-SX Controller can be used in the automation systems for housing facilities (heat and water), energy facilities, gas supply of residential and office buildings and industry, as well as systems of remote monitoring and control (SCADA-systems).

RECON controller won the first price in the Ukraine BASCOM 2010 completion!.

1 Main features

RECON-SX Controller is designed for:

- Remote monitoring the status of various objects using digital, parametric and analog sensors;

- Send alerts on certain modes of operation of equipment, changes in climate and other parameters, attempts of unauthorized access;

- Read and transfer to the control center data from meters and other devices connected to the interface RS-485/232;

- Control actuators using relay circuits (automatically or on command from the outside).

 

RECON-SX Controller can be used in the automation systems for housing facilities (heat and water), energy facilities, gas supply of residential and office buildings and industry, as well as systems of remote monitoring and control (SCADA-systems).

4 Description of the RECON-SX controller

RECON-SX controller processes the information from contacts, analog and parametric digital sensors and flow meters, produces executive commands, and transmits information on the status of sensors via cellular, satellite and VHF communications. In addition, the controller can accept control commands and queries about its state.

Controller RECON-SX is a device that has a flexible configuration. The algorithm of the controller RECON-SX under different regimes is determined by its configuration with the help of special software REconfig, supplied with the controller.

Appearance of controller RECON-SX is shown in Fig.1.

4.2 Functionality

 

4.2.1 Sensors control

RECON-SX controller receives signals from sensors of different types:

- different types of analog sensors with an output signal (0-20 V, 0-20 mA).

- sensors with potential-free contact interface, for example:

- magnetic probes of opening / closing doors and windows;
- 
motion sensors;
- 
glass break sensors;
- 
maximum allowable concentrations of various gases exceeding sensors;

- sensors with an open collector interface, for example:

- smoke detectors;
- 
sensors of water leakage;

- sensors with TTL interface, including signaling circuits of manufacturing equipment;

- air or coolant temperature sensors;

- humidity sensors.

 

4.2.2 Actuators Management

 

RECON-SX controller can manage via the relays different actuators and systems, such as:

- solenoid valves of water / gas overlap;
- 
electromagnetic locks;
- 
electric motors;
- 
electrical actuators;
- 
sirens;
- 
lighting.

Switching of controller’s relays is within user-defined algorithms, as well as by commands from a terminal, a GSM or a dispatch center.
