INTRODUCTION

Remote Station EA – 205 is designed for tele-waching and tele-control.

It's totally configurable from local and remote channel.

It's a robust and flexible equipment wide tested in many instalations:

• Water supply.
• Quality water control.
• Meteorology.
• Electrical Systems.
• Channels Control.
• Purifying Stations Control.
• Tele-alarm.

BASIC FUNCTIONS

ALARM. EA – 205 incorporate the following alarm types:

• Digital: Corresponden a los cambios de estado de las entradas digitales.
• Analogic: EA – 205 detects for each analogic signal next alarm levels: High, High - High, Low y Low – Low. Levels High y Low have associate factors of independent hysteresys.
• Internal: The internal alarms are generated by the own EA - 205 when internal failure is detected, which is notified the Control center.

CONTROL. The control function allows to act at a distance on any configured digital output.

The control orders act on the outputs establishing an impulse or a level.

DATA MANAGEMENT. EA - 205 is equipped with powerful Intel processors that added to the memory that incorporates confer a high capacity of process.

Basic management functions are:

• Data acquisition
• Alarm and historical files processing.
• Obtaining calculated values.
• Use of inputs, outputs  and logic cards.

Other functions:

• Application software update with no need to move.
• Remote access to OS.
• Access control to the equipment environment.

CONFIGURATION. The parameters that determine EA - 205 operation are configurables from the local and remote channel.

RULES:

• Marcado CE
• Year 2000 compliant
