Damocles2 is a product for monitoring and controlling digital inputs and outputs over a LAN. When a digital input is closed, Damocles2 sends an e-mail, a SNMP trap, or a text message to a specified number. As an added advantage, it can be connected to the SensDesk.com portal.Damocles2 MINI is a network device with relay outputs and digital inputs for connecting external detectors. Damocles2 can be connected to various monitoring systems. We support over 50 different third-party SNMP or SCADA applications. It is typically used as a web relay (also called IP relay, webrelay or snmp relay), an on off switch or remote power control (e.g. remote power off) for remote products, and for connecting to IoT (Internet of Things). Users also use Damocles2 to measure consumption e.g. by connecting a water meter to a digital input (S0 counter).
Four dry contacts can be connected to the Damocles2 MINI digital inputs (DI). Damocles2 MINI provides two digital relay outputs (DO) that can be controlled over a LAN.
Damocles2 is often used as a remote ethernet relay for Poseidon2. We call this the “Box-2-Box” mode. A virtual output of the Poseidon2 unit can be connected over the network to a physical relay output of the Damocles2 unit.
Alerts to changes in digital inputs – dry contact states (alarm) can be sent as a SNMP Trap, E-mail, or as a text message (SMS relay). Alerts can be delayed (for example to send an alert if a cooler door stays open for more than 5 minutes). The e-mail function supports TLS encryption. All HW group devices can send text messages (SMS) through a single central gateway, the HWg-SMS-GW. Just a single SIM card can serve all your devices. |
