Damocles2 Damocles2 24 25
Common features of the Damocles2 family
Displayed readings
• Damocles2 displays current values of all digital inputs (DI).
• Inputs feature pulse counters for connecting energy meters with S0 outputs.
• An input is considered active (for Alarm state purposes) if it is closed for more than approx.
900ms (inputs are sampled approximately every 30 ms because of S0).
• Alarm state can be set independently for each input (contact).
• If the Alarm is not assigned to any channel (SMS, Email, SNMP Trap), the alarm is not notified
and the corresponding line is highlighted in yellow at the first page (General).
• Upon Alarm, the device can send a SNMP Trap, E-mail, or SMS.
• Damocles2 notifies both the beginning and the end of an alarm (contact closing and contact
opening).
• Supports a shared HWg-SMS-GW3 gateway for texting.
• Supports SNMPv1 and SNMPv3.
• Supports e-mail authentication via TLS.

DI (Digital Inputs) – Dry contact Inputs
Dry (voltage-free) contacts can be connected to these terminals. For example door contacts.
The inputs are electrically connected to the power supply.
• Unconnected inputs read as “ 0 (Off) ”.
• Activated inputs (closed contacts) read as “
1 (On)
”, resistance against the Common pin must
not exceed 500 Ω .
Specifications:
• Maximum wiring length: 50 m
•
Supported sensors:
Any contact without external voltage (dry contact)
• Alarm settings for each DI:
• Alarm inactive
• Alarm when the contact is open or closed
• Alarm when the contact is open
•
Possible alarm responses: Common setting for all inputs
• No response
• Alarm alert sent as a SNMP trap
• Alarm alert sent by e-mail or text message (SMS)
• Alarm alert sent as a SNMP trap as well as by e-mail or SMS
•
Polling period:
approx. 900 ms
• Range of sensor IDs: DI (Digital Inputs) use ID addresses from 1 to 24
•
Input names:
Each DI can be named using up to 12 characters
• Disconnected detector indication: None, disconnected detectors read as “ O (Off) ”
DO (Digital Outputs)
Damocles2 units feature various types of digital outputs:
•
Damocles2 MINI – Relay
•
Damocles2 1208
– Open Colector
• Damocles2 2404 – Relay
Relay Output
Each output controls two relay contacts: one “
Normally Open
”
(NO)
contact (open when the
power is off and after startup), and one “ Normally Closed ” (NC) contact (closed when the power
is off and after startup).
Contact state (closed / open) is indicated by the corresponding LED.
The picture shows an example of connecting a 12 V light bulb, powered from the same source as the unit and controlled
by the Normally Open contact of output No. 4.
