Damocles2 2404: Networked remote I/O with secure SNMP v3 and IPv6


Czech version


English version

Damocles2 2404 connects 24 dry contact inputs and 4 relay outputs to a network. Secure M2M communication (HTTPs, IPv6, SNMPv3).
The product can be powered from a 12V source, over PoE, or using the Telco –48VDC standard.

Damocles2 2404 is an I/O unit for telecom applications featuring secure communication and 12V, PoE or -48V (Telco standard) power options.

Digital inputs (DI) can accept 12 dry contacts, digital outputs (DO) control 4 relays. Remote I/O can be controlled using secure SNMPv3 or HTTPs protocols or standard M2M protocols (SNMP, Modbus/TCP, XML). Support for IPv6 simplifies deployment in Telco applications.

Professional I/O signaling over a LAN

  • HTTP / HTTPs
  • SNMP v3
  • MQTT for cloud (IoT) applications
  • TLS for sending e-mail
  • -48V Telco power standard support
  • IPv6 support

Portal / Cloud support

  • I/O can be connected to the SensDesk portal.
  • The MQTT interface allows connection e.g. to the MS Azure cloud.
  • SMS GW can be used to signal Internet connectivity failure.

Applications

Damocles2 can be connected to various monitoring systems. We support over 50 different third-party NMS, SNMP, SCADA or Cloud applications. It can work as a snmp relay.

Damocles2 2404 is typically used to monitor many remote relay outputs.
Examples include fire detection, alerts from technical equipment, door contacts, etc. States of connected I/O are then displayed in the customer's monitoring system.

Text message (SMS) alerts

SMS alerts can be sent to mobile phones from Damocles2 2404 in several ways:

Text message (SMS) alerts

  • Directly over the network using SMS-GW
    A text message can be sent from the Damocles2 2404 I/O unit to a specified phone number using the HWg-SMS-GW gateway.
    No software is needed. HWg-SMS-GW should be connected to the same LAN. Sender's phone number is defined by the SIM inserted in the HWg-SMS-GW unit. Recipient's phone number is configured in the Damocles2 unit, similarly to e-mail recipients.
    One HWg-SMS-GW gateway can be shared by several devices (e.g. the STE2 WiFi/LAN thermometer in the picture).
  • With the HWg-Trigger application for Windows
    The HWg-Trigger application can run in the background on any PC with MS Windows. The application checks for device failures, disconnected sensors, or digital inputs in alarm state. Alarm status can be notified e.g. by sending a SMS to a specified number using a “HWg-SMS-GW” in the same LAN.
  • With third-party software applications
    Many SCADA (e.g. CapTemp) or SNMP (Nagios, Zabbix, ..) applications can monitor the status of the Damocles2 unit and send alerts via SMS.

  • What is the difference between Damocles2 and Poseidon2?
    – Poseidon2 reads values from various sensors and only features a few I/O inputs and outputs.
    – Damocles2 only supports dry contact digital inputs and digital outputs, does not support any sensors. Damocles2 features pulse counters at each input and Modbus/TCP protocol support in all models. Only a Damocles unit can work as the output for the Box-2-Box mode based on SNMP traps and input/sensor names.
     
  • I found several different Damocles2 devices. Are there any differences in their functions?
    Damocles2 units only differ by the number of digital inputs and outputs, power options (12V / PoE / -48V) and the type of outputs (relay / open collector).
    All Damocles2 models are the same in terms of protocols and software.
     
  • The "Telco -48V DC" power input does not indicate polarity. How should I connect the power?
    The 48V DC Telco power can be connected to this power input regardless of polarity.
    This power input accepts 30 to 60VDC.
     
  • Damocles2 2404 offers 3 ways of connecting power. Are they mutually exclusive?
    No, Damocles2 simply needs power from at least one power input.
     
  • Can I control relay outputs using the Damocles2 2404 web page?
    Yes. However, the output must be in the "Manual" mode.
    If the output is in the "Local condition" mode, change its mode to "Manual" first.
     
  • Damocles2 2404 supports pulse counting at digital inputs. What happens if the device is restarted?
    Damocles2 2404 features a non-volatile memory that keeps the counter state even if the power supply is interrupted.
    The 32-bit counter (max value: 4294967296) can be only reset over the web interface.
     
  • Can Damocles2 log values?
    Yes, Damocles2 includes an internal memory for the data logger. Data are kept even if the power goes off. The logger has a capacity for 250,000 records.
     
  • Damocles2 supports IPv6. Can it also be found in an IPv6-compatible network?
    Yes, the latest version of HWg-Config can find HW group products in IPv6 networks, too (MS Windows version only).
    The complete IPv6 address can be also seen in the product web interface.
     
  • Is it possible to connect Damocles2 2404 to a cloud?
    Yes, Damocles2 is a “cloud oriented device”. It can be connected to cloud systems as a “Cloud sensor”.
    Use the HTTP-based HWg-Push protocol, MQTT, or contact us for details.
     
  • Damocles2 supports HTTPs. Can I upload my own certificate to the device?
    Yes, a security certificate can be uploaded to Damocles2. For details, see AN46: HTTPS in Poseidon2 and Damocles2 units.
     
  • Damocles2 supports SNMPv3; can it also receive SNMP Traps in SNMPv3?
    No, Damocles2 can receive SNMP Traps but only in SNMP v1.
     
  • Do you offer a SW solution that will alert me to a failure of a Damocles2 unit?
    Yes, you can use the HWg-Trigger application that runs on any Windows PC.
    Another option is the www.SensDesk.com online service – a portal for HW group devices.
     
  • What is the maximum number of e-mail recipients for alerts?
    Damocles2 itself can send e-mails to at most 5 e-mail addresses.
    With the www.SensDesk.com online service or the HWg-Trigger application for Windows, e-mail alerts to OK/Alarm states can be sent to more than 5 e-mail addresses.
     
  • Is there an app for my mobile phone?
    Yes, several third-party apps for Android and Apple are available here: Android and iPhone mobile app for HW group products
     
  • Can Damocles2 2404 detect the presence of 230VAC (e.g. the input voltage of an UPS)?
    Yes, use the input voltage detection feature of a PowerEgg unit, or any relay with a contact connected to one of the IN1-IN4 “Dry Contact” inputs. A relay output of a Damocles2 can control the 110/230V output of a PowerEgg.
     
  • Can I connect voltage detection to DI (“wet contact”)?
    No, digital inputs (DI) are designed for direct connection of a voltage-free contact (“dry contact”), such as a door contact or a relay output.
  • What is the warranty?
    The standard warranty is 2 years, can be extended upon request.
     
  • Where can I find the prices of your devices?
    Ask our distributors, or request a quote from us (by e-mail or by filling out this form).
