Optimised to suit your requirement
We know that there is no such thing as a 'standard' application. That's why a Sentinel RTU may be supplied and configured in an enormous variety of ways.
To find the best Sentinel for your application, check the Sentinel Comparison Table
GSM/GPRS Communications
- GSM is the communication standard for all Sentinels
- SMS and GPRS are proven methods of message and data transfer
- GPRS is the most cost-effective method of data transfer for applications where data-logging is required
- SMS is simple and reliable for transmission of alarm messages
Modbus
- Why Modbus?
- Modbus is used in multiple master-slave applications to monitor and program devices; to communicate between intelligent devices and sensors and instruments; to monitor field devices using PCs and HMIs. Modbus is also an ideal protocol for RTU applications where wireless communication is required. For this reason, it is used in innumerable gas and oil and substation applications. But Modbus is not only an industrial protocol. Building, infrastructure, transportation and energy applications also make use of its benefits.
Ethernet
- The Sentinel 800 provides a 10/100 Mbit ethernet interface
- This provides communication using TCP/IP, XML, SNMP and Modbus TCP
- Access to an HTTP web server is an added feature
Enclosure
- Enclosures may be specified to suit most environments, plus oversize enclsure to house additional equipment
- Polystyrene for indoor applications
- Polycarbonate for outdoor durability
- Steel for electrically noisy environments
- Hazardous areas...
HMI
- A simple text HMI gives reassuring local status information if required
- A graphical HMI gives a complete plant overview
- Allows communication with other devices otherwise unsupported
I/O
- Remote I/O adds to the capabilities of Sentinel RTU
- Temperature sensor
- Switch input
- Analogue input
- Control relay
Power Supply
- Power supplies to suit most environments
- Universal 100-265 VAC
- 9-30 VDC
- Battery
- Battery and solar panel
