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.
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.
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.
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.
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.
This is WiFi Wireless 8 channel SPDT relay module (board) for remote management and control with Virtual Serial Port, TCP/IP, Web, HTTP API, Telnet and serial commands access. It has 8 SPDT Relays, 8 digital inputs (0-3.3V), 8 analog inputs (0-2.5V) and one UART port. Inputs can be adjusted to control relays (standalone work). Also inputs of one controller can control outputs of another over the LAN/WAN (box-to-box mode). It can send E-mails on inputs change as well. Suitable for remote control, home automation, data acquisition, sensor processing, alarm systems, PLC applications. Now with FREE Android and iOS App!
