HWg-SNMP Web relay (Model: Damocles MINI)

Control two remote relays and four digital inputs (dry contacts) with a Web interface. Switch a relay or check the input states over an IP network. The Damocles MINI is a SNMP / WEB relay that is typically used to remotely switch On/Off other devices or to measure energy consumption (using pulse counters at the inputs). When an input contact is closed, Damocles sends an email with customized text. Optionally, the email can be sent after a defined delay (for example, to send an alert if a freezer door stays open for more than 5 minutes). A typical application is the sending of an email based on Dry contact inputs, remote restart or remote relay control. Relay outputs can be controlled over M2M protocols SNMP, XML over http or Modbus/TCP. 4 DI digital inputs for contact connecting 2 DO relay outputs relay contacts (NC and NO) Sensor value out of range: sending Email or SNMP Trap to several recipients.

Features

• Ethernet: RJ45 (10BASE-T)
• WEB: Built-in web server
• Inputs: 4 digital inputs (dry contact)
• Pulse Counter: 32. bit counter on each Digital Input (for connecting S0 pulses)
• Outputs: 2 digital outputs (relays, 24VDC)
• Box-2-Box mode: Outputs are activated by alerts from other devices (Poseidon / Damocles)
• M2M communication protocols: SNMP, XML, Modbus/TCP
   
• Reaction to changes at the input: SNMP trap, Email (editable text)
• Mechanical: dimension 35 x 102 x 76 [mm] 




• Support for programmers: HWg SDK
• Supported software
  • HWg-PD Trigger: Controls other IP devices, redirects alarms to SMS
  • HWg-PDMS: Logging,conversion of pulses to energy, export to MS Excel, reports
  • CapTemp: Visualization on a map, control of outputs, alarm redirection to SMS
  • >> Third-party SNMP software

Box-2-Box mode

Changes at a dry contact input of one device (A) are sent over the network (SNMP Trap) and reflected at the relay output of the other device (B). Damocles MINI can react to changes at the inputs of another Poseidon or Damocles unit (without any additional software).

Example:
Too high temperature in the datacenter (measured by Poseidon 3266) turns on a warning red light in the IT department in another building (relay output of Damocles MINI).

Applications

• Control the relay over network – switch relay by three clicks on the mouse
• Remote Web-Relay controlled over IP (snmp / xml / Modbus/TCP)
• Pulse counter: energy consumption measurement over IP.
  Reading of the consumption in time from electrometers, flow meters, gas meters, ..
• Monitoring of sensors of door opening, motion detectors, dangerous gas, etc.
• Connecting of external inputs to SCADA systems
• Remote control over IP – Opening of entry points (doors, gates, pikes and connecting of passage sensors)
• Monitoring of back-up power supply like UPS and Diesel-engines
• Camera systems (door contacts, PIR sensors)
• Measurement of number of persons/vehicles – counting of indoor state and number of passage of persons/vehicles

Which software to use

• Configuration: UDP Config  – IP address configuration
• Event processing: PD Trigger – reacts to events
• Monitoring and logging: HWg-PDMS – Monitoring software with MS Excel reporting
• Simple Visualization: SNMPcap – I/O and sensors
• Visualization: CapTemp – Process monitoring and control
• Command line control: PosDamIO – Command-line control of inputs and outputs (see AN29)
• Other applications: Third-party software for Poseidon & Damocles
• For programmers: HWg-SDK contains interface descriptions and examples of using M2M protocols in several programming languages
  (JAVA, PHP, Borland C++ Builder 6.0, Microsoft Visual C++ 6.0, Borland Delphi 6.0, Microsoft Visual Basic & Excel VBA, VB.NET, C code for Linux, JavaScript (AJAX) Microsoft Visual C# 2005 (.NET)

 Topology

• WEB (HTML)
  The state of digital inputs and outputs is displayed on WWW page. The page is automatically reloaded every 5 seconds. On the main HTML page there are links to Flash Setup, update FirmWare and others..
• XML
  All values, the information about alarm state including, are accessible in .XML file (values.xml) and any application can easily log it from XML tags – more informations..
• SNMP
  SNMP is protocol for management of telecommunication devices, network infrastructure and related technologies. Damocles is fully controlled over SNMP – more informations..
• Modbus/TCP
  Modbus/TCP is industry standard for input of sensor values and sensors into visualization and SCADA systems. All sensors values are accessible over Modbus/TCP – more informations..
• Alarms
  • SNMP Traps
    In a case of Alarm, the device will send you SNMP Trap with a description of Alarm state to defined IP address – more informations..
  • Email
    Apart from SNMP Trap, in a case of alarm the device can send you Email with a description of Alarm state – more informations..

Technical specifications of Damocles MINI

• Ethernet: RJ 45 (10BASE-T – IEEE802.3)
• 4x Digital inputs: prepared for direct contacts connecting
• 2x Relay outputs: relay contacts NC and NO
• Device configuration:
  • UDP Config – IP address configuration, etc.. – remotely functions over the network, but only on the local segment of the network,
