Additional Product Information

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.


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.

Supported Software

  • HWg-Trigger: Control of other IP devices, alarm redirection to SMS
  • HWg PDMS: Logging, export to MS Excel, reports
  • Third-party software (SCADA systems, Modbus/TCP)
