ClockWatch Enterprise  
Relay Module
Remote Device Control The relay module is a separate hardware device used for remote device switching. With it you can remotely control devices over a network or the Internet. Devices can be remotely powered on or off with commands coming from ClockWatch Enterprise delivered over a local or wide area network.  You can control computers, peripherals or other powered devices from across the office or across the world.

The Relay module can be used to sense external On/Off conditions and to control a variety of external devices. The PC interface connection is made through the serial port.

The Relay module houses two SPDT relays and one wide voltage range, optically isolated input.  These are brought out to screw-type terminal blocks for easy field wiring. Individual LEDs on the front panel monitor the input and two relay lines. The module is powered with an AC adapter.

Using the Relay Module with Enterprise
The relay setup screen in Enterprise allows you  to open or close the two switches on the relay module. The switches can be either latched or set for a timed period and reset. The Data In option lets you check if the voltage input is 'on' (5-30 V) or 'off' (less than 5 V) on the module's input terminals.

Once the relay options are set you can choose when (or how often) you want the relay module to be triggered.

When the relay action is active Enterprise communicates with the relay module via the Enterprise Service module running on the client. The Service module sends the command to the relay module and returns the outcome to the Enterprise console.

Setting up the Relay Action in Enterprise
This example turns on switch 1 for 30 seconds.

The Enterprise console then records the action of the relay module by  listing the date, action, client and relay options.
