HWg-WLD Relay can be installed stand-alone using a 12VDC power supply and a relay output, or as a sensor connected to a Poseidon unit over the 1-Wire UNI bus. Relay outputs indicate a detected water leak or cable disconnection.
HWg-WLD Relay is supplied with a 2m (6.5ft) sensing cable.
HWg-SH2 is an IP-based remote cabinet door access control system. Front and rear doors of one cabinet (rack) can be connected to one HWg-SH2 unit.
The HWg-SH2 is IP lock control for various electronic locks. It is typically used with HWg-SH1 (H3-EM Electronic Locking SwingHandle by Southco) for cabinet door control.
The HWg-SH2 is typically used to control access to a rack in a data center. It is usually installed in hosting racks (collocation centers) or restricted-access racks. HWg-SH2 is a cost-effective solution that is easy to install.
We can provide you sensing cables of different length.
We have the sensing cable which total length is 4 m (13 ft): 2 m (6.5 ft) leader cable + 2 m (6.5ft) sensing cable, terminated.
Other sensing cable has total length 12 m (40 ft): 2 m (6.5 ft) leader cable + 10 m (33 ft) sensing cable, terminated.
Total length of other sensing cable is 52 m (170,5 ft): 2 m (6.5 ft) leader cable + 50 m (164 ft) sensing cable, terminated.
Nagios is one of the most well-known and most often used open-source software for monitoring IT infrastructures.
Nagios monitors end-user stations, IT services, as well as active network components. Its architecture is very modular and suitable for deployment in heterogeneous or *nix-based networks. There is a large and active community around Nagios that develops many additional modules or plug-ins.
HWg-WLD detects water leaks or water floods along the entire length of the sensing cable. The sensing cable detects even the smallest volume of water, ethylene glycol, or other conductive liquid. HWg-WLD can be ordered in two versions depending on the supply of power (power adapter or PoE IEEE 802.3af). The sensing cable detects as little as a few drops of the liquid, and can be used to detect condensation. After flooding, the cable can be dried and reused.
HWg-WLD features a built-in web server and SNMP support. In case of an alarm, the device sends an e-mail or SNMP trap. Alarms can be also signaled by switching a remote relay over the Ethernet. When a leak is detected, HWg-WLD activates a relay of a remote Poseidon or Damocles unit (Box-2-Box mode).
Damocles 1208 provides digital inputs (DI) and digital outputs (DO) that can be remotely controlled over the Web. The Inputs and outputs can also be controlled over the network using M2M protocols (SNMP, Modbus/TCP, XML over HTTP. Typical application of Damocles 1208 involves energy consumption monitoring by counting pulses from meters. The HWg-PDMS application converts pulses to kWh per time period and creates MS Excel output reports.
