Damocles model 2404

Product replaced by a new generation Damocles2 2404.

Damocles model 2404 is the unit of the digital inputs and outputs controlled over web. Apart from email, www graphical interface, also networks protocols are supported (SNMP, XML, Modbus/TCP and others..).

Damocles model 2404 unit accesses 24 digital inputs (galvanic isolated) and 4 relay outputs over Ethernet network. This model supports the connection of temperature sensor over RS-232 interface.

The input and output values and the relay control are accessible from any internet browser or by network protocols.

Damocles is intended for the use in industry, this version supposes mounting on the DIN rail, the unit can be situated in 19“ RACK or in the telecommunication environment.

  • 24 Digital inputs : All galvanic isolated
  • 4 Relay outputs: NO and NC contacts available
  • Temperature sensor input: Can be connected over RS-232
  • Sensor value out of range: sending Email or SNMP Trap to several recipients.

HW interface

  • 24x Digital inputs (Dry Contact)
    Damocles 2404 has 24 digital inputs (galvanic isolated) for the connection of voltage (5-20V) or contacts (door contacts, PIR sensors, motion detectors, stop sensors etc.)
  • 4x relay outputs
    Damocles 2404 supports 4 digital outputs like relay contacts. For each output 1x NC and 1x NO.
  • RS-232
    Damocles 2404 makes possible the software connection of one temperature sensor over RS-232 interface.
    Temp-232 (-10 up to +80 °C distance: up to 20 meters)


Technical specification of Damocles 2404

  • Ethernet: RJ 45 (10BASE-T - IEEE802.3)
  • Port 1: RS-232 (connector Cannon 9 Male), possibility of connection of temperature sensor
  • 24x Digital input: prepared for directly connection of contacts
  • 4x Relay output: relay contacts NC and NO
  • Device setting:
