Once configured from computer, these modules can work standalone without need of computer, tablet or smartphone. For example their outputs(relays) can be controlled by internal timers (weekly or pulses) or analog/digital inputs from current or another module (box-to-box) or they can monitor remote host and make restart based on timeout (watchdog function). At any time however the user is able to access the module from anywhere in the world in order to do manual control.
Subcategories
Time Controlled IP Relays (18)
Weekly schedule and timer activated IP Relays with computer/webserver interface. Once the relay boards are configured, they can work without any computer, smartphone or tablet. However it is possible to control them anytime when necessary.
IP I/O Relay Modules (7)
These modules can activate their outputs (relays) based on analog/digital/temperature inputs levels like PCL. Once, their levels and modes are configured, they can work standalone without need to be accessed from computer/smartphone. However they can be monitored/controlled anytime from all over the world.
Box to Box IP Modules (11)
These modules support the so called feature "box-to-box" or "point-to-point" or "machine-to-machine". One module, installed on a location, can control another single module, installed on another location over the network, without need of computer. More information about this function - here.
IP Watchdog Relays (14)
The purpose of these relay modules is to monitor remote host and to "keep it alive" based on ingoing/outgoins ICMP timeout.They monitors the availability of the LAN devices and automatically restarts them in case of failure. Unresponsive device (computer, router, switch, IP camera, WiFi AP...) is detected by unavailable no reply to PING. In such a case, the denkovi relay board can reset the device in order to get in back working.
