IP WatchDog HWg-WR02a: Ping restarter
Monitors the functionality of a device over IP (PING/WEB) or serial line (RS-232), automatically restarts it upon failure. Web watchdog monitors two independent channels. Industrial version.
IP WatchDog WR02a (ping restarter) periodically monitors the functionality of a device by transmitting or receiving a specified “I'm alive and OK” signal over IP or RS-232. If the correct reply is not received in time, the device is restarted with a relay.
IP WatchDog can monitor two devices (two independent channels, two 110/230VAC relays). Industrial applications benefit from DIN rail compatibility.
Failures are detected with five distinct methods, separately for each channel (Ping Tx/Rx, Web page request/push, RS-232 data). Web WatchDog WR02a allows flexible configuration – method of functionality detection, switchoff time when restarting.
* 2 channels / 2x 110/230V / 16A relay
* Methods of detecting functionality
o ICMP PING (transmit / receive)
o Request for a Web page (requesting / waiting for a request)
o RS-232 (waiting for a specific sequence of characters)
Features:
# Ethernet: RJ45 (10BASE-T)
# WEB: Built-in web server, manual reset and output control, logging
# Functions: Two channels, independent per-channel monitoring
# Methods of detecting functionality per channel:
* Ping Push: IP WatchDog periodically sends PING requests
* Ping Request: IP WatchDog waits for a PING from a specified IP address
* Web Push: IP WatchDog periodically checks the availability of a given web page (web server)
* Web Request: IP WatchDog waits for a request for its internal WEB page
* RS232 Rx: IP WatchDog waits for a sequence of characters in the RS-232 data stream
# Channel output: DO relay output (NO/NC, 230V/16A AC)
# Manual control of the relay over WWW (with a password) - can be used as a 110V Web relay
# Security ensured with user passwords and a configurable range of allowed IP addresses
# FirmWare update can be performed over the WWW interface
# Log & Time: Automatic time sync over NTP (TIME), event logging
# Installation: Installation in 10 minutes, no software is necessary
# Tip: Outputs can be turned on/off manually over the web interface
# Dimensions: 145x90x45 [mm]
Usage examples
# Operation monitoring / IP restart
* Servers / routers
* IP video cameras
* WiFi links / access points
* Industrial systems
# Connectivity monitoring
* Activation of a back-up link
* Detection of connectivity outage (relay >> horn)
* Monitoring of ADSL and cable modems
* Security and access control systems |
