The EDAC 700-RTU is a remote terminal unit that allows remote monitoring, alarming, interrogation, and control of various equipment types.

The EDAC 700-RTU has 20 physical I/O points that can be individually configured as either Analogue or Digital Inputs or as Digital Outputs.  The following options are supported on any I/O point:

Digital Input - Normally Open

Digital Input - Normally Closed 

Analogue Input 0-1v

Analogue Input 0-10v

Analogue Input 4-20mA

Digital Output

Using the configured I/O the EDAC700 RTU can monitor security sensors, high/low temperatures, high/low liquid levels, equipment power on/off detection and equipment failures. 

The EDAC700 communicates I/O status by means of voice messaging by landline telephone or cell phone, alphanumeric pager messaging and SMS text messaging.  

The EDAC700 RTU utilises its Roster, Timeframe, Call List and I/O Group functions to allow cost-effective management of plant and equipment.  The correct technical expertise will be called when a particular fault occurs.  The engineer or technician will then be able to remotely assess the urgency of the situation and take the appropriate action.

Analogue sensors (4-20mA etc) can report a spoken value with engineering units. The analogue reading can also be sent as part of an alphanumeric paging message, or as part of a text message to a cell phone.

The EDAC700 RTU has the ability to be interrogated remotely using a touch-tone phone for a status update of its inputs or remote manual on/off control of equipment such as pumps, motors or lights using its output functionality.

The EDAC700 RTU can be configured with its keypad or via its RS232 port using a PC and Hyperterm, or using remote dial in modem access. 

You can also communicate to external devices such as data loggers by connecting them to the EDAC700 RTU RS232 port.
